Abstract

In these lectures I will give an overview of the rich mathematical structures that characterize the wave solutions of some of the most important nonlinear partial differential equations, such as the Schrödinger equation. In doing so I will illustrate how beautiful pieces of mathematics, developed using different tools, not just coming from analysis, have been generated over the years in order to answer some of the most fundamental questions for these equations, such as existence and uniqueness of solutions for example. Along the way I will formulate open questions and possible new directions of investigation.

AMS-MAA Joint Invited Address

Gravity's Action on Light: A Mathematical Journey

Thursday, August 2, 10:00 a.m. – 10:50 a.m., Plaza Ballroom A, B, & C, Plaza Building

Arlie Petters, Duke University

Abstract

The gravitational fields of stars, black holes, and galaxies act on light propagating near them, casting magnification patterns in space. Such optical phenomena have wide-ranging physical applications, including detecting extrasolar planets and testing for a fifth dimension of the universe. Assuming no background in astrophysics or cosmology, this talk will take you on a mathematical journey unveiling the intriguing properties of these beautiful magnification patterns.

Inclusion-exclusion in Mathematics: Who Stays in, Who Falls out, Why It Happens, and What We Should Do About It

Friday, August 3, 11:30 a.m. - 12:20 p.m., Plaza Ballroom A, B, & C, Plaza Building

Eugenia Cheng, School of the Art Institute of Chicago

Abstract

The question of why women are under-represented in mathematics is complex and there are no simple answers, only many contributing factors. I will focus on character traits, and argue that if we focus on this rather than gender we can have a more productive and less divisive conversation. To try and focus on characters rather than genders I will introduce gender-neutral character adjectives "ingressive" and "congressive" to replace masculine and feminine. I will share my experience of teaching congressive abstract mathematics to art students, in a congressive way, and the possible effects this could have for everyone in mathematics, not just women. I will present the field of Category Theory as a particularly congressive subject area, accessible to bright high school students, and contrast it with the types of math that are often used to push or stimulate those students. No prior knowledge will be needed.

MAA Invited Address

Snow Business: Scientific Computing in the Movies and Beyond

Saturday, August 4, 11:00 a.m. - 11:50 a.m., Plaza Ballroom A, B, & C, Plaza Building

Joseph Teran, University of California Los Angeles

Abstract

New applications of scientific computing for solid and fluid mechanics problems include simulation of virtual materials in movie visual effects and virtual surgery. Both disciplines demand physically realistic dynamics for materials like water, smoke, fire, and soft tissues. New algorithms are required for each area. Teran will speak about the simulation techniques required in these fields and will share some recent results including: simulated surgical repair of biomechanical soft tissues; extreme deformation of elastic objects with contact; high resolution incompressible flow; and clothing and hair dynamics. He will also discuss a new algorithm used for simulating the dynamics of snow in Disney’s animated feature film, “Frozen”.

Mathematical Medicine: Modeling Disease and Treatment

Thursday, August 2, 9:00 a.m. - 9:50 a.m., Plaza Ballroom A, B, & C, Plaza Building

Lisette de Pillis, Harvey Mudd College

Abstract

Immune system dynamics have proven to play an increasingly central role in the development of new treatment strategies for immune-related diseases such as type 1 diabetes and certain cancers. The critical importance of the immune system in fighting such diseases has been verified clinically, as well as through mathematical models.

Many open questions remain, however, including what may lead to non-uniform patient responses to treatments, and how to optimize and personalize therapy strategies. Mathematical models can help to provide insights into the mechanisms that may be influencing patient outcomes. In this talk, we will present a sampling of mathematical models that help us to simulate immune system interactions, disease dynamics, and treatment approaches that may slow, or even stop, disease progression.

 

MAA James R.C. Leitzel Lecture

The Relationship between Culture and the Learning of Mathematics

Saturday, August 4, 9:00 a.m. - 9:50 a.m., Plaza Ballroom A, B, & C, Plaza Building

Talitha Washington, Howard University and National Science Foundation

Abstract

How do we ensure that our mathematics is culturally inclusive? Why have issues with minority participation not been resolved? Unfortunately, even with our best intentions, our implicit biases impact the mathematics we teach and learn. We all can take an active role to ensure the strength of our future mathematical community, which should also be a reflection of our Nation. I will share how to infuse various cultures in learning mathematics that can better help educate those of diverse backgrounds which will broaden the participation of those doing mathematics.

 

AWM-MAA Etta Zuber Falconer Lecture

Finding Ellipses

Friday, August 3, 9:30 a.m. - 10:20 a.m., Plaza Ballroom A, B, & C, Plaza Building

Pamela Gorkin, Bucknell University

Abstract

Ellipses make frequent appearances in our lives: Kepler’s laws of planetary motion involve ellipses and a medical procedure involving kidney stones known as lithotripsy uses them as well. We see ellipses in architecture and in President’s Park South we find a park called simply “The Ellipse.” What properties of the ellipse make it so important? How can we construct an ellipse? We begin with questions like these, providing some unfamiliar answers. Then we study three seemingly unrelated problems in mathematics, chosen from linear algebra, complex analysis, and projective geometry, and we show how the solution to each of these problems relies on finding ellipses.

FAIL: A Mathematician's Apology

Thursday, August 2, 1:30 p.m. - 2:20 p.m., Plaza Ballroom A, B, & C, Plaza Building

Laura Taalman, James Madison University

Abstract

The job of being a mathematician primarily consists of long periods of failure punctuated by short bursts of success which later seem to be somewhat obvious...but that’s what we love about it! And, as it turns out, 3D printing kind of works the same way. In this talk we’ll take a journey through many mathematical and 3D printing failures and try to laugh about it the best we can.

Laura Taalman Bio

Pi Mu Epsilon J. Sutherland Frame Lecture

The Singular Uniformity of Large Random Systems

Wednesday, August 1, 8:00 p.m. - 8:50 p.m., Plaza Ballroom A, B, & C, Plaza Building

Peter Winkler, Dartmouth College

Abstract

A random structure could be anything, yet somehow, when that structure is composed of many small parts, it often turns out to be shockingly predictable---at least, in a probabilistic sense. A random graph on a million vertices, for example, has a long list of characteristics each with high probability.

In an attempt to understand this phenomenon, we'll take a little tour from zero-one laws to variational principles, contrasting graphs and permutations along the way.

 

NAM David Harold Blackwell Lecture

Continuous, Discrete, or Somewhere in Between: An Introduction to Time Scales with Applications

Friday, August 3, 1:00 p.m. - 1:50 p.m., Plaza Ballroom A, B, & C, Plaza Building

Raegan Higgins, Texas Tech University

Abstract

Since Stefan Hilger's landmark paper in 1988, progress has been made in the unification and extension of discrete and continuous analysis. The broad idea is to prove a result once for a dynamic equation where the domain of the unknown function is a time scale \(\mathbb{T}\), which is an arbitrary, nonempty, closed subset of the real numbers.

In this talk, we will use the exponential function \(e^{pt}\) to introduce the theory of time scales. Considering a certain second-order linear delay dynamic equation, we establish some sufficient conditions which ensure that every solution oscillates. The obtained results unify the oscillation of second-order delay differential and difference equations.

Our interest in delay equations has lead us to study a certain area of mathematical physiology. We are using mathematical models to understand how behavioral disruption of the circadian clock can lead to glucose dysregulation. In this talk, we present some preliminary results.
