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

Interdisciplinary course creation: Exploring Patterns Between Mathematical Structures and Literary Narratives

March 13, 2025

UBC

Interdisciplinary education can provide opportunities for students to experience familiar disciplines through new perspectives, revealing connections that can enrich their understanding of both subjects. This talk presents a first-year course developed collaboratively at the American University... 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

On two Notions of Flag Positivity

March 11, 2025

ESB 4133 (PIMS LIBRARY)

The totally positive flag variety of rank r, defined by Lusztig, can be described as the set of rank r flags of real linear subspaces which can be represented by a matrix whose minors are all positive. We show that, for flag varieties of consecutive rank, this equals the subset of the flag... Read more

A motivic Weil height machine for curves

March 10, 2025

The rational points of a hyperbolic curve over a number field map to the set of augmentations of the associated motivic algebra. An expectation, closely related to the Grothendieck section conjecture, is that the set of augmentations which are locally geometric is equal to the set of rational... Read more

DETECTING CLUSTER PATTERNS IN TENSOR DATA USING LIE THEORY

March 7, 2025

ESB 2012 and Zoom

I'll introduce a class of cluster patterns for tensor data used in pattern matching, outlier detections, statistics and signal processing. Then I will show they are all shadows of a general pattern detected efficiently by algebra, specifically Lie theory. It is a new direction for the subject... Read more
