Phase transitions and conic geometry

April 26, 2018 - 3:30pm - Vincent Hall 16
Ordway Visitor - Joel Tropp
Abstract: A phase transition is a sharp change in the behavior of a mathematical model as one of its parameters changes. This talk describes a striking phase transition that takes place in conic geometry. First, we will explain how to assign a notion of "dimension" to a convex cone. Then we will use this notion of "dimension" to see that two randomly oriented convex cones share a ray with probability close to zero or close to one. This fact has implications for many questions in signal processing. In particular, it yields a complete solution of the "compressed sensing" problem about when we can recover a sparse signal from random measurements. This talk is designed for a general mathematical audience.
Based on joint works with Dennis Amelunxen, Martin Lotz, Mike McCoy, and Samet Oymak.

Fractal solutions of dispersive PDE on the torus

May 3, 2018 - 3:30pm - Vincent Hall 16
Burak Erdogan
Abstract: In this talk we discuss qualitative behavior of certain solutions to linear and nonlinear dispersive partial differential equations such as Schrodinger and Korteweg-de Vries equations. In particular, we will present results on the fractal dimension of the solution graph and the dependence of solution profile on the algebraic properties of time.
