## Past Events

## Molly Fenn, NC State, Gerrymandering: Math at the Supreme Court

Gerrymandering, the act of drawing political maps to achieve a desirable election outcome, has been increasingly in the news as cases wind their way to the Supreme Court and as the country approaches a new census in 2020. In this…

Classical Schur Q-functions describe characters of a queer Lie superalgebra, projective representations of a symmetric group and provide solutions of a BKP hierarchy. This talk is devoted to properties of a generalization of Schur Q-functions - factorial Q-functions, including a particular important case of shifted…

Triangle Math Teachers' Circle Workshop (sponsored by American Institute of Mathematics) will be held at NCSU, Math Department, on Saturday February 10. This event is aimed at current and future teachers, math education students and anyone who is interested in creative approaches to teaching mathematics through…

Phylogenetics is the branch of mathematical biology concerned with constructing evolutionary relationships between collections of species. These lectures will introduce these models, in particular emphasizing the ways that algebraic statistics can be used to analyze properties of the models. Viewed…

Recently, there has been an increasing interest from the community in real-life complex system modeling. The most popular example is provided by systems where the number of agents is so large, that only a statistical description (reminiscent to the statistical…

I will discuss formulations and algorithms for computing sparse optimal controls in systems governed by PDEs. These sparse solutions can guide the placement of control devices in applications. After reviewing results for elliptic and parabolic PDEs, I will focus on recent work on sparse…

The Association for Women in Mathematics (AWM) will be hosting our weekly brown bag lunch. Attendees bring their own lunches, and have the opportunity to be in a casual discussion environment, while we provide a tasty treat! AWM is NOT…

Suppose you want to convince someone that you know the solution to a problem, but you don’t want them to learn any- thing about the solution. How can you do it? Such a protocol is called a zero-knowledge proof. In…

We consider the action of the group SL_n x SL_n on the space of m-tuples of n x n matrices by simultaneous left-right multiplication. Visu Makam and the speaker recently proved that invariants of degree at most mn^4 generate the invariant ring. This…

Several topics will be presented in this talk. In the first part, we consider some portfolio optimization problems with stochastic dividends, stochastic volatility or delays. The Hamilton-Jacobi-Bellman (HJB) equations are derived, which are second order nonlinear PDEs. We then establish…

An increasing number of scientific and enterprise data sets are multidimensional, where data is gathered for every configuration of three or more parameters. For example, physical simulations often track a set of variables in two or three spatial dimensions over…

Historically, the study of the collection of concordance classes of knots has focused on understanding its group structure while devoting relatively little attention to the natural metric induced by the 4-genus. Cochran and Harvey investigated the metric properties of the maps on concordance induced…

Find out more »## Antonio Marigonda, University of Verona, Italy, Sovereign debt management problem with currency devaluation

We propose a model of sovereign debt management, where a state trade some bonds to service the debt with a pool of risk-neutral competitive foreign investors. At each instant of time, the government decides which fraction of the GDP (subject…

Find out more »## Michael Ruddy, NC State, What is Inquiry-Based Learning?

There is an increased interest in alternatives to the traditional lecture-based instruction in math courses. Inquiry-Based Learning (IBL) is a teaching philosophy that challenges students to think more like mathematicians by posing questions rather than presenting established facts. In this…

Find out more »## Cynthia Vincent, NC State, Convex sets and the geometry of numbers

Quite a large polygon can squeeze between the integer points in the plane, but what if it has to be symmetric bout the origin (and avoid all other integer points)? In this talk, I’ll discuss Minkowski’s theorem, which bounds the area of such shapes,…
