# Events for November 29, 2017 from General and Seminar calendars

## AWM Women in Math Mentoring Lunch

## Number Theory Seminar

**Abstract:** Rudin-Shapiro polynomials are a special sequence of trigonometric polynomials with all coefficients equal to 1 or -1 which do not become too large. In this talk I will discuss conjectures of B. Saffari and H. Montgomery regarding the distribution of these polynomials, and outline how these conjectures were resolved by making use of an analogy to random walks on compact groups. Prerequisites will be kept to a minimum.

## Numerical Analysis Seminar

## Postdoc Colloquium Series

**Abstract:** Chemical reaction networks are directed graphs in which each edge represents a chemical reaction. The most basic kinetics to assign to reaction networks are those of mass-action, first introduced 150 years ago by Guldberg and Waage: the rate at which each reaction occurs is proportional to the product of the concentrations of its reactants. The systematic study of the resulting polynomial ordinary differential equations began in the 1970s, and in recent years, this area has seen renewed interest, due in part to applications to systems biology. This talk will survey progress on long-standing questions pertaining to the dynamics of reaction systems, particularly their multistationarity and long-term stability, using methods from combinatorics and polyhedral as well as toric geometry.

## First Year Graduate Student Seminar

## AMUSE

**Abstract:** While it may seem like the title of this talk has a typo, I really meant it! Many of society’s most pressing challenges require the development of new technologies, which in turn often require the development of new materials. Materials discovery, however, is extremely time-consuming. Because of this, the field of materials science is rapidly trying to adapt new methods and frameworks to accelerate the discovery of materials. In this talk, I will provide some examples from my own research program where we have used advanced mathematical and computational techniques to discover new materials or improve existing ones. The examples I will talk about use ideas from mathematical optimization, search, informatics, artificial intelligence, operations research, optimal learning, and even game theory to discover new materials. I will show how using these techniques we have been able to discover and develop new materials at a rate that is significantly faster than using traditional methods.
