Restriction theory, signal recovery and applications

October 10, 2025

ESB 2012 and Zoom

A classical problem in signal recovery is to determine whether a finite signal can be recovered from its Fourier transform with missing values. This problem has been studied by many authors starting with the seminal papers by Matolsci and Szuks in the 70s and Donoho and Stark in the late 80s.... Read more

Math-Bio: Mathematical Models of Tobacco Use Dynamics: Products, Flavors, and Networks

October 8, 2025

ESB 4133

Mathematical biology offers powerful tools to tackle pressing problems at the interface of health and public policy. In this talk, I will share two vignettes demonstrating how mathematical and simulation modelling can be applied to tobacco regulatory science. The first uses a Markov state... Read more

Entropy properties of nonlocal diffusion equations

October 7, 2025

ESB 4127 (PIMS)

Nonlocal diffusion equations are evolution equations which resemble the heat equation except that, instead of describing an ensemble of a large number of particles undergoing Brownian motion, the particles are instead governed by a jump process. In this talk, I will explain a variational... Read more

Algebraic models for functor calculus

October 7, 2025

There is a striking and useful analogy between equivariant homotopy theory and functor calculus. In the equivariant setting, Greenlees conjectured that the category of rational G-spectra has an algebraic model - meaning it is equivalent to the derived category of an abelian category with...

Brauer groups and Neron-Severi groups of surfaces over finite fields.

October 6, 2025

MATH 126

For a smooth and proper surface over a finite field, the formula of Artin and Tate relates the behavior of the zeta-function at 1 to other invariants of the surface. We give a version which equates invariants only depending on the Brauer group to invariants only depending on the Neron-Severi... Read more

Extremal Kähler metrics on modifications

October 2, 2025

ESB 4127

I will present the invariance of extremal Kahler manifolds under a suitable class of bimeromorphic morphisms.

Focusing mostly on the cscK (constant scalar curvature Kähler) case, I will show how the main result is obtained as a consequence of a general uniform coercivity estimate for... Read more
