Take off your shoelaces, tie them up, and fuse the two ends together to form a continuous lace without ends. Now you have a mathematical knot. Two knots are the same if you can move, bend, and stretch one until it looks exactly like the other. Now take a flashlight and point it at your knot. The shadow of your knot on the wall is called a knot diagram or a knot projection.
One common way to study knots is via their invariants, quantities that are associated with the knot that do not change regardless of how the knot is presented. One such invariant is the Jones polynomial. In this talk, we define the Jones polynomial of a knot and discuss what the Jones polynomial tells us about a knot.

Simplicial complexes are versatile objects in the intersection of graph theory, combinatorics, topology, and geometry. While mathematicians have always appreciated the fact that simplicial complexes are extremely powerful in spite of being easy to define and relatively easy to work with, their usefulness in realworld applications has increased dramatically just in the last decade or so.
In this talk, I will first discuss the definition and the basic constructions that can be performed with simplicial complexes, toggling back and forth between combinatorics and topology. I will then give an overview of some of their recent applications in signal processing, neuroscience, data analysis, and social sciences. I will in particular describe ongoing work by several undergraduates at Wellesley College in which certain types of political systems and their interactions are modeled by simplicial complexes.
This talk should be accessible to anyone who has had some exposure to combinatorics (basics of combinations and permutations).

To avoid misleading anyone, this talk will not be about the sociology of topologists! "Social choice" is a model for decision making in economic, social, and political contexts. For example: suppose that each person gets to vote on their favorite location where they would like to place a statue on an island. Is there a fair way based on these votes to choose the location? This will turn out to be a topological, even a homotopical, problem, depending on the topology of the island. In this talk we will explore social choice models and answer the question about when they exist using algebraic topology.
The purpose of this talk is to serve as an advertisement for algebraic topology and basic category theory. I will not assume any background other than calculus (in particular the notion of continuity so that I can give an intuition about topology). Familiarity with abstract algebra will help, but I will err on the side of defining what a group is, and I will give a crash course in category theory.

Today's popular AI is mostly software, algorithms, and big data processing. Mathematics powers most of these AI techniques that are rapidly integrated into every aspect of our society and are useful for a vast array of applications. AI agents only understand numbers, more specifically, blobs of zeros and ones. In this talk we will use undergraduate mathematics to make an AI agent process our natural language, recognize what she sees, and make intelligent decisions. We will work out simple examples that have wide applications in the Artificial Intelligence sphere. This is an extremely undergraduate friendly talk and you only need to have calculus and linear algebra backgrounds.

Florian Frick, Carnegie Mellon University
Online Event 1:30 pm – 2:30 pm EDT/GMT4
How do you fairly divide rent among roommates, a necklace among thieves, or a pizza between friends? Such questions of fair division can often be understood with the tools of geometry and topology — even for those problems that are not geometric to begin with. We will discuss how to do this, and why topology is useful for problems that appear to be unrelated to topology. In particular, we will explore a relation between fairly splitting a necklace and inscribing shapes into curves. No prior knowledge of topology is needed, and this talk is available to all who are familiar with some linear algebra or multivariable calculus.

In 1943, J. L. Woodbridge of Philadelphia submitted the following problem to American Mathematical Monthly: “Show that n cuts can divide a cheese into as many as $(n+1)(n^2  n + 6)/6$ pieces.”
This question and its solution are deeply connected to the study of collections of lines in $mathbb{R}^2$, planes in $mathbb{R}^3$, and more generally hyperplanes in $mathbb{R}^n$. We will explore the solution and a more general version: given n (hyper)planes in a real, ddimensional vector space, how can we figure out the number of chambers of an arrangement of hyperplanes, without necessarily being able to see and count them?
There are many wonderful solutions to this question. We present one provided by the VarchenkoGel’fand ring, which is the ring of functions from the chambers of the arrangement to the integers with pointwise addition and multiplication. Varchenko and Gel’fand gave a simple presentation for this ring, which can be computed using simple facts about linear algebra.
We will assume very little background but expect that the audience is familiar with linear independence and dependence. We will give a ringtheoretic solution to this problem, so it may be helpful (but not necessary) to be familiar with quotient rings.

Ethan Bloch, Bard College
Online Event 3:00 pm – 4:00 pm EDT/GMT4
In this talk we discuss the interplay between curvature and the distance between points on polyhedra. We start by discussing the curvature of polyhedra, which is concentrated at the vertices, and we then consider the question of whether or not a shortest path between two points on a polyhedron can pass through a vertex. We then discuss an attempt, not yet successful, at finding a polyhedral analog of Myers' Theorem for smooth surfaces, which relates positive curvature to distances between points. Along the way we consider some questions about the unfolding of polyhedra (for example, unfolding a cardboard box so that it is flat). This talk is open to all.

Generalized splines on a graph G with edge weighted by ideals a commutative ring R are Rvertex labelings such that if two vertices share an edge in G, the vertex labels are congruent modulo the edge ideal. When R is a principal ideal domain, we introduce collapsing operations that reduces any simple graph to a single vertex and carries along the edge ideal information. This corresponds to a sequence of surjective maps between the associated spline modules, and leads to an explicit construction of an Rmodule basis in terms of the edge ideals. We also solve an interpolation problem, i.e., given a partial vertex labeling, when can it can be extended to a generalized spline?

Given a family of convex sets in R^d, how do we know that their intersection has a large volume or a large diameter? A large family of results in combinatorial geometry, called Hellytype theorems, characterize families of convex sets whose intersections are not empty. During this talk we will describe how some bootstrapping arguments allow us to extend classic results to describe when the intersection of a family of convex sets in R^d is quantifiably large. The work presented in this talk was done in collaboration with undergraduate students.

Campus Walk Above Kline 9:30 am – 1:00 pm EST/GMT5
In a rare occurrence, the planet Mercury will pass in front of the Sun on the morning of November 11. However, this is not a celestial event that one can view by looking to the heavens with an unaided eye, since
a) Mercury is very small compared with the Sun, and
b) You shouldn't look directly at the Sun.
In order to view the transit (clouds permitting) the Physics Program will have a telescope with a solar filter set up on Campus Walk, just up the hill from Kline. Drop by anytime from 9:30am until the transit ends at 1pm to check out this planetary alignment for yourself.
Note the next chance to view a Mercury transit from Bard will be on May 7, 2049.

RKC 103 5:00 pm – 6:00 pm EDT/GMT4
Drawing on arguments from The Parthenon and Liberal Education (SUNY, 2018), a monograph recently coauthored with my Bard College Berlin colleague Geoff Lehman, I will point to the resonance of the work in number theory, astronomy, and harmonics of Philolaus, a near contemporary of Socrates, with central features of the design principles of the Parthenon. In this way, I hope to show that the Parthenon can be seen as a mediator between the early reception of Ancient NearEastern mathematical ideas and their integration into Greek thought as a form of liberal education, as the latter came to be defined by Plato and his followers. Prominently in its pursuit of harmonia (harmony; joining together) without resolving tensions between opposites, the Parthenon engages dialectical thought as we encounter it in Plato's dialogues and in ways that are of enduring relevance for the project of liberal education.

The idea that worlds exist beyond our solar system, exoplanets, dates back to the Greek times, but it was not until 1992 that the first exoplanet discovery was accepted by the scientific community. Detections of exoplanets continued at a crawl until the Kepler mission began in 2009. To date, over 3,700 exoplanets have been confirmed using a variety of techniques. The types of exoplanets detected range from incredibility hot, Jupitersize exoplanets to Earthlike exoplanets that may be habitable for life.
First, we’ll discuss the motivation behind exoplanet science and explore the subject from a historical perspective. We will investigate how some of the detection methods work and discuss their relative successes. Finally, we will conclude by exploring the reflected light of exoplanets in more detail and will discuss two methods of modeling that light.

Executive Director, Riverbend Community Math Center
Hegeman 204 1:30 pm EST/GMT5
We will discuss the differences among several prevailing math instruction philosophies, including traditional math instruction, conceptual math instruction, inquiry/project based learning, and math circle instruction. We will talk about the motivations behind some of these approaches, the reasons that math instruction is changing, and how to incorporate the various approaches when working with students.
Amanda Serenevy has been active with the Math Circle movement to connect mathematicians with young students interested in mathematics for many years. As a graduate student, Amanda first became involved with Math Circles as an instructor in Bob and Ellen Kaplan's Math Circle program in the Boston area. In November 2006, Amanda accompanied a group of American mathematicians during a trip to Moscow and St. Petersburg to learn about Russian math outreach programs. Amanda regularly coorganizes events for mathematicians and teachers from around the country who are interested in starting their own outreach programs, and has mentored many new Math Circle leaders. Amanda continues to offer Math Circles in the South Bend area. In 2006, Amanda and her husband Dean founded the Riverbend Community Math Center. Amanda continues to serve as the executive director, designing curricula and lessons, and leading professional development sessions for teachers and handson math activities for people of all ages.

Suppose you're one of a group of people responsible for a decision: choosing which applicant to hire into a job; deciding what food to have available at a banquet; or choosing who's going to represent you in Washington, D.C. How can you do it? Social choice theory is the branch of mathematics that studies how groups can make decisions. We'll take a look at some problems, some solutions, and some paradoxes that result when groups try to make decisions.

There is a lot of talk about math being &lquo;everywhere&rquo; in &lquo;daily life,&rquo; and I would argue that most (all?) mathematicians understand how to find it. But the process of finding math in unexpected places is something that most of us learned by osmosis rather than consciously.
Many South Indian Hindus have at least one god in their home—a statue that they worship every day. The daily &lquo;puja&rquo; often involves making a design out of rice powder in front of the god. We will look at two variations of this design, called a Hridaya kolam. (Hridaya = heart, kolam = designs made from powder in South India.)
After learning to make the two standard designs, we will embark on an exploration to find some mathematics in them—making algorithms, generalizing, looking for structure, explaining what we find, coming up with useful notation, deciding on definitions, and so on. Different students will be free to follow different paths through the exploration.
Sunita Vatuk has a Ph.D. in differential geometry from Princeton University. As part of her teaching at the University of Colorado (Boulder), Rutgers University (Piscataway), and City University of New York she has worked extensively with high school math teachers. That work sparked an interest in the existence and nature of mathematical thinking outside of research mathematics, including but not limited to origami and textile production. This talk is based on over 80 interviews with kolam experts and hundreds of designs she learned as a Fulbright scholar affiliated with the Institute of Mathematical Sciences, Chennai.

"It is notoriously hard to give a satisfactory answer to the question, 'What is mathematics?'" —Timothy Gowers
"One proposal, made in desperation, is 'What mathematicians do.'" —Ian Stewart
This women's art form is not part of academic research mathematics, and most of the experts in it are not formally educated, but the kolammaker and the mathematician do share many patterns of thought. The range of mathematical connections found in kolams make it a particularly rich arena in which to explore that elusive definition of mathematics, by focusing on mathematical thinking outside of academia.

Digital images surround us. They are found in our computers, iPhones, televisions, and more. Because they are so integrated into our lives, there is a constant need to manipulate and investigate these images. Anything that one might want to do with a digital image will inevitably involve some kind of mathematics, whether it be linear algebra, geometry, or topology. In this talk, we will introduce not only the topology of digital images, but topology in general. We'll discuss some of the main ideas in topology and use them to figure out what topology would mean in a digital setting. Our newfound knowledge of digital topology will then allow us to dene a digital version of the Hopf fibration, a function between spheres of different dimensions which links together circles in a beautiful and profound way. This talk will be accessible to undergraduates.

In the final stages of a long and costly drug discovery process, a drug compound is introduced into humans as part of a clinical trial. A clinical trial is a research study with a predefined protocol and is conducted in different phases. In oncology, as many as 60% of drug compounds that reach the last phase (Phase III) fail this final step. This high failure rate may reflect inappropriate evaluation of compounds in preceding Phase II trials, in which the primary endpoint is often binary tumor response, based on the Response Evaluation Criteria for Solid Tumors (RECIST). This motivates the search for alternative Phase II endpoints. In this talk, we will introduce clinical trials and survival analysis to contextualize the problem. Then we will describe our work evaluating alternative categorical and continuous tumor measurementbased endpoints for their ability to predict overall survival using data from real clinical trials.

COMPACTNESS OF RIGID GRAPH
Given a graph G, a framework is a straight line embedding of a G into ddimensional space. Two frameworks of G are equivalent if the corresponding edges in the two frameworks have the same length. Given a collection of equivalent frameworks of G, a framework is compact if the distance between all pairs of vertices is minimal among the collection. We are mainly considering generic frameworks, in which the coordinates of the vertices of G are algebraically independent. In this paper, we studied compact frameworks in R and R^2.

Recurrence relations arise in many fields of study. To solve a recurrence relation is to find an explicit formula for the numbers of the sequence generated by the recurrence. Informally, an ordinary generating function is a power series whose coefficients are the terms of
a given sequence. In this talk, we will introduce the method of generating functions for solving linear recurrence relations with constant coefficients and apply this method to solve the Fibonacci recurrence
relation.

Breast tumor development is influenced by the individual properties of the tumor cells but also by other noncancerous cells within its microenvironment. Based on experimental data, each tumor cell’s intrinsic properties are modeled, taking into account properties like cancer cell type and receptor numbers. In addition, we model the microenvironment’s influence on individual cancer cell properties, such as migration and proliferation. Then using agentbased modeling, we examine how individual cells interact with their microenvironment to form tumors and show how changes in that environment affect the tumor’s growth and invasion. From these results, we make predictions for potential therapies based on the interplay between the tumor and its microenvironment.

A line arrangement is a finite collection of lines in the plane. We can study this combinatorially by looking at intersections of lines. We can study this topologically by looking at the complement (in complex projective space). We can ask if the combinatorial information forecasts the topological information. When this does not occur, we obtain two different geometric arrangements; we call this a Zariski pair. There is no such pair of up to nine lines. Examples have been found with thirteen lines by Rybnikov in 1998 and with twelve lines by GuervilleBalle in 2014. Together with Amram, Sun, Teicher, Ye, and Zarkh, we investigate arrangements of ten lines. Together with an undergraduate student Liu last year, we investigate arrangements of eleven lines.

With three detections and counting, the Advanced LIGO gravitationalwave observatories have opened a new window into the Universe. For now, all the detected gravitationalwaves originated from collisions of two black holes. The effect that these gravitationalwaves have as they pass through space is to stretch and compress spacetime, much like sound waves stretch and compress the air. To understand the challenge of detecting this effect here on Earth, imagine (if you can) that a reasonably strong gravitational wave changes the length of one kilometer by one thousandth of a proton's diameter. At this level of sensitivity, quantum mechanics and the Heisenberg uncertainty principle start playing a significant role and if we want to listen further into the Universe, we need to manipulate the quantum nature of light to our advantage. In this talk I will give an overview of gravitational waves, how LIGO detects them, and why quantum mechanics matters when measuring distances with such precision.

At a dinner party, each guest is assigned a seat along a long table, which seats 12 people. However, when all guests arrive, they decide to change things a little up by swapping seats. In order to minimize the amount of chaos, they have to follow the following three rules: a guest can keep their seat; two guests sitting next to each other or across the table can swap seats; three or more guests can swap seats in a cyclic
fashion, provided that each person is moving one seat to the left or to the right or across the table. Assuming that all guests have showed up, how many possible seating rearrangements are there? Now consider the graph on the left. We want to place dominoes along some of the edges of this graph so that each vertex is covered by exactly one domino. We call any such placement of dominoes a domino tiling. How many domino tilings of this graph exits?
In this talk, we will explore the connection between these two problems by defining what the factorial of a graph is.
Prerequisites: A familiarity with graphs and counting arguments is a plus, but not
required.

In this talk, we investigate the important question of how many zombies are required to catch and eat a person in an enclosed structure. We model the structure with a graph, and we assume that the person can move much faster than the zombies. The minimum number of zombies required to catch an intelligent person is called the zombie number of the graph. This is a variation on the "cops and robbers" game from graph theory, which can be used to define the treewidth of a graph. We will discuss how the zombie number of a graph relates to the treewidth, and we will determine which graphs have zombie number 1 and 2. This talk will be accessible to anyone who is taking or has taken a 200level mathematics course.

Splines are piecewise polynomial functions that are often used to approximate complicated functions. They arise in various branches of applied mathematics, computer science and engineering. Applications include computer graphics and computer modeling, airplane design, and approximating solutions to partial differential equations. More recently, splines have been studied for their algebraic properties, and their defining equations have been generalized to arbitrary rings.
In this talk, I will describe Integer Splines on a graph, where both the edges and vertices of the graph are labeled with integers. The vertex labeling is called a spline if the difference between vertex labels is divisible by the corresponding edge label. I will report on recent work with Bard students, and open problems for the future.
Prerequisites: Familiarity with Linear Algebra and modular arithmetic is helpful, but not required.

The purpose of this talk is to explore the interplay between mathematics and physics by taking a closer look at the theory of Electricity and Magnetism. We will start with the normal physicist's formulation of Maxwell's equations and then rewrite them from the perspective of a mathematician. This will allow us to describe what charge is as a mathematical object. We will then give a mathematical generalization of Maxwell's equations motivated by string theory and explore how physical phenomena can inform our understanding of the underlying mathematical structures. This talk should be accessible to anyone who has taken Math 213 or above.

Given any 3 shapes in R3 (e.g., a piece of ham, a hunk of cheese, and a slice of bread), does there exist a single plane that simultaneously cuts each shape into two pieces of equal volume? Can any shape in R2 be dissected into four pieces of equal area by some pair of perpendicular lines? By exploiting hidden geometric symmetries, we will show how equipartition problems such as these can be solved using powerful techniques from the seemingly unrelated eld known as algebraic topology. For instance, the positive answer to the rst problem above { the socalled Ham Sandwich" Theorem { ultimately reduces to a very deep result of Borsuk and Ulam: for any continuous map from a sphere to a plane, there must exist a pair of antipodal points on the sphere whose images coincide. While fairly advanced mathematics is not too far away, this talk requires only a familiarity with the intermediate value theorem to be understood. All are welcome to attend!

A very useful number associated with polyhedra is the Euler characteristic, which in the 2dimensional case is V  E + F, where V, E and F are the number of vertices, edges and faces of a polyhedron, respectively. In this talk we consider the question of whether the Euler characteristic is locally determined, which means that it can be calculated as the sum of numbers determined in a neighborhood of each vertex of the polyhedron; there are combinatorial and geometric versions of this question, where the geometric version goes back to an idea of Descartes, from before Euler. We will then ask the analogous
question regarding the CharneyDavis quantity of a polyhedron, which in the 2dimensional case is 1  (1/2)V + (1/4)E  (1/8)F. This talk should be suitable for all students who are currently in Math 261 (Proofs and Fundamentals) or beyond.

In 1909 Arthur Wieferich proposed a way to attack Fermat's last theorem by introducing a variant on Fermat's little theorem. His idea has since been refined and now forms what is known as the "Wieferich Conjecture". Even though Fermat's last theorem has been proved, the Wieferich conjecture remains open and a major area of research in modern number theory. In this talk, I will explain the Wieferich conjecture, its modern geometric interpretation, and my current research project. This talk should be suitable for all students who are currently in Math 261 (Proofs and Fundamentals) or beyond. In particular, we will make extensive use of modular arithmetic.

By exploiting hidden symmetries, we will show how equipartition problems such as these (as well as a variety of other questions from combinatorial geometry) can be solved using techniques from the seemingly unrelated field of algebraic topology. For instance, the positive answer to the first problem above  the socalled "Ham Sandwich" Theorem  ultimately reduces to a deep result of Borsuk and Ulam: for any continuous map from a sphere to a plane, there must exist some pair of opposite points on the sphere whose images coincide. Although group theory, topology, number theory, and even Fourier analysis are all truly at play, no background in these fields is required to appreciate the fascinating interplay of the continuous and the discrete at the heart of topological combinatorics. All are welcome to attend!

Inverse problems are a large class of both theoretical and applied problems that have captivated the mathematical community for over half a century. During this time numerous applications have arisen in in a variety of fields, such as medical imaging and cloaking. In the first half of this talk I will discuss, by example, general inverse problems and how they arise in the real world. In the second half I will focus specifically on spectral inverse problems, starting with the classic "Can you hear the shape of a drum?" problem in the case of the sphere. Finally I will present an analogous result for semiclassical Schrödinger operators.

If you have a rubber band and a pegboard, how many polygons can you make that have only one peg in the center? The answer to this question is highly interesting to string theorists, who use shapes like these to write equations for the predicted "extra" dimensions of the universe. We'll talk about the way mathematicians use intuition from string theory to make mathematical discoveries.

In physics, supersymmetry is a pairing between the carriers of mass and energy appearing in theories of subatomic particles. These physical theories can be described using graphs known as Adinkras. We will tour the mathematics of supersymmetry by illustrating how we can construct Adinkras using binary cubes and error correcting codes. We will discuss recent results that allow us to give a geometric interpretation of these physical theories using Grothendieck’s theory of dessins d’enfants, or “children’s drawings.” This will lead us to consider spin structures and discrete Morse functions as a natural part of supersymmetry.

Navigation and spatial memory are two of the most vital functions of the brain. Without the ability to construct an internal map of our environment and remember how to get from one place to another, we would be lost (literally)! In 2014, the Nobel Prize in Physiology and Medicine was awarded to John O'Keefe for the discovery of place cells, a particular type of neuron essential to spatial memory. In this talk, we will consider an algebraic method to store spatial information received from place cells, and explore ways to reconstruct topological features of a spatial environment from that stored data.

In this talk I will give an overview of the exciting and growing field of image processing, by introducing how images and video can be modeled and manipulated mathematically. I will give examples of the typical problems that are studied in this discipline, and present an array of applications in medicine, astronomy, atmospheric science, security, navigation systems, and others in information technology. Also, I shall present the research problem of image reconstruction under "optical turbulence", i.e. the optical phenomenon caused by light rays being refracted to form distorted images at the observer's location: this typically occurs when looking at objects at a distance in hot climates, or underwater in the presence of temperature gradients (i.e., when the water temperature is not the same at different locations). The results of an imaging recovery algorithm will also be illustrated.

We live in an environment that is constantly changing. On a large time scale, climate change has a global effect on the dynamics of plant populations. On a smaller scale, there are seasonal changes of local habitats, for example, flooding and drying of wetland habitats. In this talk, I will present a spatial perspective of the effects of environmental changes. What happens when the suitable habitat of a population changes its location, or its size over time? Are there limits of the population’s ability to cope with these spatial changes? How does the life history of plant species affect their persistence in the presence of environmental change? I will present a set of mathematical models aiming at answering these questions.

Wolbachia are intracellular bacteria that are widespread in mosquito species and are known to limit the spread of insectborne human pathogens including dengue, malaria and worms. The success of Wolbachia is attributed to a variety of ways in which the bacterium manipulates its host to promote fitness of infected females and increase transmission as bacteria are passed from mothers to offspring. Although longproposed as a tool for the control of dengue, until recently it was thought that Anopheles mosquitoes, the vectors of human malaria, were unable to be infected by Wolbachia. Recent observations in Burkina Faso showed stable but low persistence of Wolbachia infections in Anopheles mosquitoes. Here, I present an ordinary differential equation model of Wolbachia infection in Anopheles mosquitoes developed in collaboration with students from the Summer Research Program in Epidemiology at the Harvard Chan School of Public Health. We demonstrate the persistence of Wolbachia at low prevalence in the context of varied reproductive phenotypes. Through analysis of our model, we determine which phenotypes are most important for persistence of Wolbachia infection, aiding survival of Wolbachia infected laboratory populations.

One of Erdos' greatest contributions to geometry was his problem on distinct distances that asks: what is the least number of distinct distances among n points. This seemingly innocent inquiry inspired many other related questions, some of which are still being worked on today. In this talk we will start with an introduction to the original distinct distance problem and then move on to some related questions, such as the unique distance problem and heavy lines. There will be a special emphasis on crescent configurations that were tackled by the Number Theory and Harmonic Analysis group in the Williams undergraduate summer research program in 2015.

The language of experience and evaluation: Logical and linguistic investigations into subjective judgment
ReemKayden Center Room 101 Abstract: We’re all in the business of evaluation. We evaluate basketball players and beers, movies and motels, students and teachers. Philosophical discussions both contemporary and classical have elevated the notion of a judge or point of view in explaining the central puzzling feature of evaluation — the tugofwar between the subjective genesis of and objective standards of correctness for evaluative judgments. In recent years there has been a torrent of work at the intersection of philosophy and linguistics on socalled "faultless disagreements" — disputes (e.g. over whether vanilla ice cream is tastier than chocolate ice cream) that seem to concern mere personal preferences. I argue that popular accounts misconstrue the meaning of evaluative expressions and that the claims at issue concern norms of experience. On the way to this conclusion, we’ll touch on a number of issues in logic and linguistics: quantification, genericity, modality, and aspect.
Alex Anthony is a PhD candidate at Rutgers University, Department of Philosophy. After completing his undergraduate studies at Wesleyan University he participated in Summer Schools in Logic, Language and Information in Ljubljana, Slovenia and in College Park, Maryland before enrolling at Rutgers.

RKC 111 Butterfly wings, snowflakes, and Romanesco cauliflower are all great examples of the beautiful symmetry found in nature. But symmetry also has a second life as a powerful tool for reducing the complexity of mathematical problems. In this talk I'll introduce this second life of symmetry and highlight some of its unlikely applications, including a very impractical scheme to get rich by reassembling broken eggshells.

RKC 115 Mathematics plays an increasingly crucial role in understanding the mechanisms underlying brain activity. This talk introduces fundamental problems in neuroscience and explores how mathematical analysis may provide new solutions, impacting technological advances such as prosthetics and artificial intelligence. We focus on information processing in sensory systems, and study how data may be encoded by neuronal dynamics. Using a largescale network model of the visual system with nonlinear dynamics, we demonstrate how stimuli may be efficiently compressed by sensory systems and reconstructed through novel signal processing techniques. Especially drawing from the theory of differential equations, probability, and linear systems, this talk highlights the central role of applied mathematics in the interdisciplinary field of computational neuroscience, linking principles from physics, biology, computer science, and engineering.

RKC 111 While walking and running are everyday activities for most of us, researchers still have a rather limited understanding of how the brain and body interact to produce human locomotion. In this talk, I will offer some examples of how mathematics can be used to help explain the neural processes involved in walking and running. These include identifying the processes involved in minimizing energy expenditure, analyzing the effect of mechanical artifact on mathematical analyses of electroencephalography during walking, and using mathematical modeling to examine dynamic causality between neural sources. I will then discuss how mathematical models, experimental analysis, and the development of appropriate mathematical measures can interact to help us answer some remaining fundamental questions about neural activity during gait.

When one person is given a piece of information in a network and every person is allowed to pass this piece of information to exactly one person at any discrete time step, we give an optimal algorithm to pass this information to every person in the network in the fewest number of time steps. A similar algorithm is used to find the optimal starting person. These algorithms are applied to specific classes of graphs and also interpreted to give applications to cybersecurity. ** Only an algebra background needed for the talk

A lecture by Rachel RoeDale, Associate Professor of Mathematics, Skidmore College
Hegeman 204 Several experimental and clinical studies have documented that the order in which chemotherapy drugs are administered affects the outcome of cancer treatment. I present a brief discussion of a simple mathematical mechanism to explain this order dependence in conjunction with more detailed models which investigate the specific relationship between drug order and treatment response in breast cancer chemotherapy and gastric cancer chemotherapy. In all cases, I simulate treatment by bolus injection and employ a pulsing condition to indicate cell kill. I then extend this type of treatment model to my current investigation which considers the dynamics of bacteria and yeast populations. I model these populations as competitive species and simulate antibiotic treatment to investigate how this treatment alters the behavior and dynamics of the populations perhaps leading to an infectious state.

A presentation by Dr. Robert Moniot, Chair, Department of Computer & Information Science, Fordham University and Dr. Damian Lyons, Director, FRCV Lab, Fordham University
RKC 100 The first presentation overviews the Computer and Information Science (CIS) department at Fordham University and introduces the CIS graduate program in Computer Science.
In the second presentation, three pieces of ongoing research at the FRCV Lab will be overviewed: visual homing, multirobot exploration and formal analysis of robot behavior to generate performance guarantees.
Visual homing is a navigation approach first proposed as a model of inspect behavior. Because it requires only visual image comparisons, it is a simple and general approach. However, goal directed motion in the absence of distance information can be error prone. Nirmal & Lyons (2013) proposed a stereocamera based visual homing whose performance improves on that of regular visual homing.
In deploying a team of robots to explore an area for search and rescue or CWMD missions, it is preferable for the team to spread out and cover the area as quickly as possible. It is difficult to design a simple, decentralized dispersion algorithm that works with a wide range building layouts. Liu and Lyons (2014) developed a simple yet general potential field approach based on the concept of generating a potential in empty space that reflects coverage.
It would be preferable to deploy autonomous teams rather than teleoperated robots to handle CWMD missions given the potential for widespread and serious damage. However, autonomous robots can behave very unpredictably. Formal verification techniques, such as modelchecking, could be applied to this problem, but the requirement parallel activities, timeconstrained and probabilistic action, and realnumber variables all cause extreme statespace size issues. Lyons and Arkin (2012) propose an approach to verification of behaviorbased robot systems based on a process algebra model of recurrence a dynamic Bayesian network for probabilistic filtering. They show that this can be used for efficient verification of performance guarantees and validate the guarantees with extensive experimentation.

A lecture by Yan Zhang, University of California, Berkeley
Hegeman 308 Adinkras are graphical tools created for the study of representations in supersymmetry. Besides having inherent interest for physicists, adinkras offer many easytostate and accessible open problems for mathematicians from different trades (by the end of the talk, I will have pretended to have known stuff about Clifford algebras, posets, coding theory, switching graphs, and algebraic topology...), but especially combinatoralists! I will include my original results, but mostly, I just want to share my enthusiasm for these pretty objects. No specialist knowledge required.

Hegeman 308 We present an urban network that takes into account how streets and neighborhoods interact and influence each other. This twomode urban structure presents another approach to analyze urban environments. We use GIS to construct a network map of an American city and then apply network analysis to evaluate how the network structure influences such features as traffic flow, density and housing considerations. Also, given the rise of African cities, where some are being completely designed and developed in lieu of developing organically, the results of this project will make recommendations for effective metropolitan growth structures.

Hegeman 204 A lecture by Zachary Hamaker '08
A sorting network is a way to reverse a list of numbers by swapping adjacent entries in the list using as few swaps as possible. We will discuss what a random sorting network looks like. To do so, we will highlight the role of simulation in mathematics, use combinatorial and probabilistic techniques and explore what it means to describe a random object. There will be open problems. There will be surprising conjectures. We will look at the best pictures. The target audience is all Bard students.

Natasha Komarov

We consider a pursuitevasion game played on a graph in which the pursuer—here referred to as “hunter”'—is not constrained by the graph but must play in the dark against a “mole.” It turns out that the graphs—which we will call “hunterwin”—on which the hunter can guarantee capture of the mole in bounded time have a nice characterization: a graph is hunterwin if and only if it is a lobster. We also define an optimal hunter strategy (and consequently an upper bound on maximum game time on hunterwin graphs) and note that an optimal hunter strategy need not take advantage of the hunter's unconstrained movement.

Hegeman 204 A lecture by
Brigitte Servatius
Worcester Polytechnic Institute
A barandjoint framework in the plane with degree of freedom 1 is a mechanism. A famous simple example of a mechanism is the Watt engine, also called Watt's parallel linkage. It consists of two grounded bars (or links) whose free ends are connected by a third link. In Watt's patent specification of 1784 for the Watt steam engine he explains that the midpoint of the connecting link is constrained to move on a (good approximation to a) straight line. This fact is still used in automobile suspensions, allowing the axle of a vehicle to travel vertically while preventing sideways motion.
It is well known that the operations of 0extension and 1extension, the so called Henneberg moves, may always be done on a mechanism to preserve the degree of freedom infinitesimally and generically. But, is it true that for a given generic realization of a mechanism these operations may be performed without restricting the motion?

Daniel CristofaroGardiner
The Institute for Advanced Study
The "Ehrhart polynomial" is an important tool for counting lattice points in triangles and other polygons. An Ehrhart polynomial has a "period", and the relationship between the coordinates of the vertices of a polygon and the period of its Ehrhart polynomial can be quite mysterious. Daniel CristofaroGardiner will present recent joint work with Aaron Kleinman relating the periods of the Ehrhart polynomials of some simple triangles with recursive sequences like the Fibonacci numbers and the Pell numbers. Interestingly, this is linked to a curious staircase arising in a special geometry called "symplectic" geometry.

Branden Stone
Mathematics Program
The Hilbert series of a module over a commutative ring is a generating function that captures many invariants of the module. In the case of zero dimensional standard graded rings, the Hilbert series is a polynomial and we call the coefﬁcients the hvector. As it turns out, the number of such hvectors of length n is bounded above by the nth Fibonacci number. In this talk, we will define the Hilbert series and give some basic examples. We will also discuss the sequence deﬁned by the number of hvectors of a given length and its relation to the Fibonacci numbers and partitions. This talk will be accessible to anyone who has taken (or is currently taking) linear algebra.

Hegeman 308 A lecture by
Tristan Hübsch
Professor of Physics, Howard University
Symmetry is recognized throughout nature and our descriptions of it. Mathematically, it requires that varying some quantity results in no observable change: rotate a wellformed clover leaf by 120 degrees, and it looks the same. Supersymmetry is such a transformation, the only one known to guarantee our Universe from decaying into another, and then another, and again, and again. Yet, this transformation maps physical quantities measured in terms of ordinary numbers into quantities measured in numbers that square to zero. The study of this supersymmetry being underway for about half a century, it is surprising that a complete (socalled offshell) representation theory is only now emergingand it includes certain binary encryption codes, of the kind used by your browser to insure that the downloaded page is a faithful copy of the original on a website! This fascinating syzygy of diverse ideas opens doors to new discoveries in physics, mathematics and encryption alike. This talk does not assume any advanced background in mathematics or physics.
Refreshments will be served afterwards in the Albee Math Lounge.

Networks are all around us! From our social interactions to the neurons in our brains to financial markets, we find network structure. Network science can help us to better understand how these complex systems in our world work. We will begin our discussion with a brief introduction to network science; including the components of a network, how we measure the center of a network and other network metrics. I will present some interesting applications of network science that you may encounter in your daily life. Finally, I will conclude with an overview of three ongoing projects in network science. The first looks at how use network structure to classify a financial market. Second, we will explore how Twitter can be used to predict an event such as a protest or revolution during the time of the Arab Spring. Finally, I will present a project examining the links between water, energy and social networks in developing countries and plans of how this multilayered network can be synchronized to build a resilient and robust network, which could supply more people with these resources.

ReemKayden Center A Math Teachers' Circle is a community of math teachers, math professors, & professional mathematicians, coming together to do fun, openended math. Typically, we engage in openended, brainteasing, fun problems that require us to think in new and creative ways. Then, we talk about the math together and share ideas and resources for bringing the math into the classroom. Each teacher will receive manipulatives and other takeaways related to the problems at hand, and dinner will be served.
Please join us for an afternoon designed to celebrate the excitement of math, to deepen our understanding of both content and math practice standards, and to explore classroomready resources. For more information about math teachers circles in general, visit http://www.mathteacherscircle.org/

RKC 102 A Lecture by Amir Barghi, Candidate for the Position in Mathematics
In the Firefighter Problem, a fire starts at a vertex of a graph (a tree in an orchard or a forest). In discrete time intervals, the fire spreads from burning vertices to their neighbors (from burning trees to the ones close by) unless they are protected by one of the firefighters that are deployed every turn. Once burned or protected, a vertex remains in that state. This process terminates when the fire can not spread any longer. In the case of finite graphs, firefighters wish to minimize the damage or the time that the fire rages. When a fire starts in an infinite graph, the key question is whether the fire can be stopped. In this talk, two different models for an infinite forest on a flat terrain will be introduced and conditions under which a fire can be stopped will be discussed.

Rational numbers can construct the real numbers by using the absolute value metric. Under different metrics, rationals can construct different types of numbers. In particular, the pnorm evaluates how much a prime, p, is a factor in a given rational. We will explore some consequences of the pnorm and what kind of numbers it creates from the rationals.

Go ahead, put on your ndimensional goggles. To be sure, we’re not talking n=3 (for kids and the fainthearted). Think higher; so high your head has almost disappeared; so high your neighbors are all suspiciously alike and almost perfectly different. As thrillseeking mathematicians, we’ll go where no man has gone before (well, except for those other thrillseeking mathematicians). We’ll explore some mindbending highdimensional phenomena, including: Surprising methods for eliminating surprises, lowdistortion interdimensional travel, what the laws of large numbers don’t tell you, how geometry and probability are sometimes the same thing, easily mowing your hyperspherical lawn, and where to look for your hat in a highdimensional room.

When is it possible to glue two graphs together? When is it possible to slice a large graph? What does "firstorder logic with parity quantifiers" mean, and what does it have to do with gluing and cutting graphs? In this talk I will answer all four of these questions. No previous knowledge of parity, firstorder logic, graphs, scissors, or glue will be assumed.

Mathematical models are used across the sciences to help understand complicated processes, e.g., the life expectancy of a nuclear reactor, the spread of a contaminant, the risk of a disease outbreak, the sustainability of an endangered species, and so on. In this talk, we introduce sensitivity analysis as a tool for studying the dynamics of such a model and identifying which parameters have a significant impact on its output. This analysis plays a crucial role in informing viable and effective management strategies while also helping to quantify the effects of uncertainty in parameter values. Examples from biology and epidemiology will be presented throughout the talk.

RKC 111 A lecture by
Courtney Gibbons
University of Nebraska, Lincoln
If you love math and games, you've probably done a few Sudoku puzzles in your day. Have you noticed that all Sudoku puzzles have some properties in common (the sum of every row is 45, for instance)? We'll see how to formalize these observations by using polynomials to set up the Sudoku "game space." Then we'll figure out how to solve specific "game boards" in this space using some tools from (abstract) algebra.
Don't worry; even if you haven't taken any abstract algebra, you'll be able to follow this talk (all you really need is a background in Calculus II).

A proper coloring is an assignment of a color to each vertex of a graph G so that neighboring vertices have different colors. Graph coloring has been a motivating topic for much of graph theory.
Suppose we change the color of just one vertex in a graph coloring. Can we get from one coloring to another by a sequence of vertex changes so that each step along the way is a proper coloring? The answer is of course yes, if we are allowed an unlimited number of colors. What is the fewest colors we can have for this to work?
We introduce a new graph called the coloring graph to analyze this situation. The coloring graph, and similar constructions, can be used to solve problems ranging from counting the possible number of graph colorings to modeling spin conﬁgurations in atoms.

Hegeman 308 A lecture by
Elizabeth Russell
Department of Mathematical Sciences
United States Military Academy
In this talk, we will discuss the sets of the complex plane on which chaos occurs (the Julia set) for families of iterated polynomial and rational maps. Specifically, we will see how wellknown Julia sets like the basilica, rabbit, and rat behave when perturbed by the addition of a pole at the origin. Some of the objects that will appear in the talk are Cantor sets, Cantor sets of simple (and not so simple) closed curves, and Sierpinski curves.

The cards in the game of SET are an excellent model for the finite affine geometry AG(4,3). We will explore how to use the game to visualize the structure of the geometry. We will focus on complete caps, which correspond to largest possible collections of cards with no sets. There is an interesting structure to these caps, and even more, the geometry can be partitioned into disjoint complete caps together with a single point closely related to the caps.

The card game SET is an awardwinning, addictive game played with a special deck of 81 cards. We can learn a lot about the game through combinatorics, probability, linear algebra and geometry. In this talk, we will explore some of the things we can learn about the game by looking at the mathematics behind it, and we'll also see that you can learn more about mathematics using the game to help with visualization. If you would like some practice with the game before the talk, go to www.setgame.com for the rules and a Daily Puzzle.

Recent advances in DNA selfassembly have resulted in nanoscale graphs: cubes, octahedrons, truncated octahedra, and even buckyballs, as well as ultrafine meshes. These constructs serve emergent applications in biomolecular computing, nanoelectronics, biosensors, drug delivery systems, and organic synthesis.
One construction method uses karmed branched junction molecules, called tiles, whose arms are double strands of DNA with one strand extending beyond the other, forming a 'sticky end' at the end of the arm that can bond to any other sticky end with complementary WatsonCrick bases. A vertex of degree k in the target graph is formed from a karmed tile, and joined sticky ends form the edges. Another construction method 'threads' a single strand of DNA through the graphical structure and then uses short 'staple' strands to fold the DNA into the desired geometric realization of the graph. A third method uses circular single strands of DNA to trace the faces of a topological embedding of the graph.
We use graph theory to determine optimal design strategies for biologists producing these nanostructures, and conclude with a discussion of how the same mathematics, on the macroscale now, may be adapted to space applications.
This is joint work with Greta Pangborn, with undergraduate research
participation.

A generating function is is said to be "a clothesline on which we hang up a sequence of numbers for display." We will define and give examples of this notion. Further, we use the concept of a generating function to count the number of ways there is to make change for a dollar. Also, we will briefly explore where generating functions appear in mathematical research, in particular, commutative algebra.
The talk should be accessible to anyone who has taken Calculus II.

Flat surfaces (such as a cube or tetrahedron with the vertices removed) show up in a variety of mathematical areas. Their structure can be studied using Delaunay triangles, which in most cases are uniquely determined by the surface. As a surface is deformed, its Delaunay triangles change, and the way in which they change can give us a surprising amount of information about the surface. The only prerequisites for this talk are knowing what a
2x2 matrix is, and a certain level of comfort with abstract constructions.

Though the terminology may be unfamiliar, you have certainly seen a maximal abelian selfadjoint subalgebra (masa) of the complex matrices in your linear algebra course: the algebra of diagonal matrices. The notion of orthogonality for a pair of masas in M_n(C) is simple to describe, but surprisingly deep and relates to many areas of mathematics. In this talk, we'll consider the fascinating and important open problem of nding complete sets of pairwise orthogonal masas in the n x n complex matrices. We'll look at a few dierent ways to think about the problem, as well as why one might be interested in a solution, and an assortment of related questions. If time permits, I'll talk a bit about how orthogonal masas have come up in current research on structure theory of nite von Neumann algebras.This talk will be accessible to anyone who has had a course in linear algebra

Most people remember working with polyhedra in elementary and high school: cubes, prisms, tetrahedra, pyramids, etc. Euler's formula states that if V is the number of vertices, E the number of edges and F the number of faces of a polyhedron, V + F = E + 2. This is a beautiful and useful formula  but can't we do more? Can we get a similar theorem if we change some of our hypotheses? How does Euler's formula change if we allow polyhedra to be in dimension 4 or 5 or n? What if we look at angles of polyhedra instead of the number of faces? We will look at a number of examples as we generalize Euler's formula in these directions and others. We will end with a glimpse of open questions about angles in polytopes. No specific math background will be assumed, but curiosity is expected!

A fractal is a mathematical shape that exhibits the same structure at a range of different scales. Among the most famous fractals are the Julia sets, which arise in a simple way from polynomials and complex numbers. In this talk, I will introduce Julia sets and discuss some of their basic properties. I will then indicate a connection between Julia sets and certain groups of functions on the unit circle. This talk should be accessible to students who have taken Proofs and Fundamentals. Some familiarity with groups would be helpful, but is not necessary.

The Legendre Polynomials are orthogonal polynomials that have deep connections to mathematical physics. For example, they arise when solving the Laplace equation in spherical coordinates. It is also the case that the Legendre Polynomials are extensively studied for their numbertheoretic properties. In this talk we will describe some of these properties as well as discuss some open questions surrounding the Legendre Polynomials. This talk should be accessible to students who are currently taking Proofs and Fundamentals (though some group theory will be used at the end).
