Jason Brown, Dalhousie University, Independence Polynomials and Their Roots
Independence polynomials are generating functions for the number of independent sets of each cardinality in a graph G. In addition to encoding useful information about the graph (such as the…
Sara Maloni Affiliation, University of Virginia, Mapping class group actions on character varieties
In the first part of the talk we will discuss famous topological and dynamical questions and conjectures about character varieties and the associated action of the mapping class group. In…

SAS 4104Differential Equations and Nonlinear Analysis Seminar: Cass Miller, UNC, Toward a New Generation of Models to Simulate Two-Fluid Flow in Porous Media
Two fluid flow in porous medium systems is an important application in many different areas of science and engineering. Overwhelmingly, it is necessary to mathematically model the behavior of applications…
Andrew van der Poel, NC State, Reductions & Problems which Computers are Slow to Solve
SAS 2102We all tackle hard problems everyday, like finding a parking spot in the Dan Allen Deck. However, there are special types of problems which are hard even for a computer…
Teaching and Diversity Statements
An afternoon discussion/workshop by Jo-Ann Cohen on preparing teaching and diversity statements for the job search. Note unusual time!
Yerkin Kitapbayev, NC State, American Options Pricing Under Stochastic Volatility Models via Picard Iterations
Daniels 371This paper studies the valuation of American options for a general one-factor stochastic volatility model. Using the local time-space calculus on surfaces we derive an early exercise premium representation for…
Biji Wong, CIRGET, Twisted Mazur Pattern Satellite Knots and Bordered Floer Theory
Bordered Floer theory has proven quite useful for studying satellites. In this talk, I'll discuss how to use gradings in bordered Floer theory to study the Floer thickness, 3-genus, and…
Undergrads Union Grads (UUG) Math Grad School Applications Workshop
SAS 2102UUG is holding a Math Grad School Applications Workshop. We will have a presentation about applying to grad schools in mathematics. We will touch on the topics of personal statements,…

SAS 4104Roman Shvydkoy, University of Illinois, Chicago, Analytical perspectives on the emergence phenomena in systems of collective behavior
Systems governed by laws of self-organization arise in many different contexts including biology (swarming behavior of animals), social (opinion dynamics, social networks), technological (cosmology, control, robotics), and others. A particular challenge in studying such…
John Nardini, NC State, The Topology of Data
SAS 2102The 21st century has seen a boom in the production of data as well as methods to analyze data. One such methodology is Topological data analysis (TDA), where concepts from topology are used…

SAS 4104Maxim Bichuch, Johns Hopkins University, Robust XVA
We discuss the reasons for the introduction of Valuation Adjustments as a consequence of the financial crisis of 2007-9. We introduce an arbitrage-free framework for robust valuation adjustments. An investor…
Kornelia Bastin and Johnny Gillings Jr., NC State, News Methodologies and Predicting and Deterring Outbreaks of Malaria (INFORMS presentation)
Daniels 371Kornelia Bastin, OR PhD Student People are faced with an overwhelming amount of news, only some of which comes from credible sources and is fact verified. The main idea behind…
Jordan Massad, Mathematics and Statistics at Sandia National Laboratories: A Perspective from an Engineering Scientist
Sandia National Laboratories is a federally funded research and development center that develops and applies science, technology, and engineering solutions for pressing national security challenges. Mathematics at all levels of…
Yu-Min Chung, UNC Greensboro, Summaries of persistence diagrams and their applications to data science
Topological Data Analysis (TDA) is a relatively young field in both algebraic topology and machine learning. Tools from TDA, in particular persistent homology, have proven successful in many scientific disciplines. Persistence…
