Zeta functions of algebraic varieties and special values

March 24, 2025

Math 126, UBC Math department

In 1966, Tate proposed the Artin-Tate conjectures, which expresses special values of zeta function associated to surfaces over finite fields. Conditional on the Tate conjecture, Milne–Ramachandran formulated and proved similar conjectures for smooth proper schemes over finite fields. The... Read more

UBC/PIMS Early Career Award Lecture

ESB 2012 and Zoom

Deep learning models are often seen as black boxes, their complexity stemming from integrating numerous architectural components across multiple layers while being trained on high-dimensional datasets with carefully tuned hyperparameters. In this talk, I will present recent work uncovering... Read more

Martingale and analytic dimensions coincide under Gaussian heat kernel bounds

March 19, 2025

Given a strongly local Dirichlet form on a metric measure space that satisfies Gaussian heat kernel bounds, we show that the martingale dimension of the associated diffusion process coincides with Cheeger's analytic dimension of the underlying metric measure space. More precisely, we show that... Read more

Math-Bio: Analysis of a 3-component reaction-diffusion system with linear cross-diffusion

March 19, 2025

ESB4133

In this talk, I will present a roadmap for deriving minimal necessary conditions for diffusion-driven instability for a 3-component reaction-diffusion system with linear cross-diffusion. For the reaction kinetics, we postulate and formulate a new 3-component phenomenological molecular... Read more

Relative Poincare duality in nonarchimedean geometry

March 17, 2025

Math 126

While the etale cohomology of Z/p-local systems on smooth p-adic rigid spaces is in general hard to control, it becomes more tractable when the spaces are proper. For example, in the proper case it is finite-dimensional and has recently been shown in work of Zavyalov and of Mann to satisfy... Read more

Dispersive estimates for the discrete Schrödinger equation on a honeycomb lattice

March 13, 2025

PIMS Lounge

The discrete Schrödinger equation on a two-dimensional honeycomb lattice is a fundamental tight-binding approximation model that describes the propagation of electrons on graphene. By the Fourier transform on the honeycomb lattice, the free Schrödinger flow can be represented by a certain... Read more

Stochastic Localization with Non-Gaussian Tilts and Applications to Tensor Ising Models

March 12, 2025

We present generalizations and modifications of Eldan's Stochastic Localization process, extending it to incorporate non-Gaussian tilts, making it useful for a broader class of measures. As an application, we introduce new processes that enable the decomposition and analysis of non-quadratic... Read more
