Math-Bio: Herbivory and temperature mediate coral reef halo dynamics

October 22, 2025 - 2:00 pm to 3:00 pm

ESB 4133

‘Reef halos’ are rings of sand, barren of vegetation, encircling reefs. However, the extent to which various biotic (e.g., herbivory) and abiotic (e.g., temperature, nutrients) factors drive changes in halo prevalence and size remains unclear. The objective of this study was ... Read more

A random walk approach to high-dimensional critical phenomena

October 22, 2025 - 3:30 pm to 4:30 pm

ESB 2012

The study of critical phenomena in lattice statistical mechanical models such as percolation and spin systems has a long history in both physics and mathematics. A central problem is to prove existence and calculate the values of the critical exponents that govern the ... Read more

A geometric approach to regularity for optimal transport maps

October 24, 2025 - 3:00 pm to 4:00 pm

ESB 2012 and Zoom

The first regularity results for maps optimizing an open class of cost were proved by Ma-Trudinger-Wang (2005) using a key inequality which they introduced (based on a classical strategy of Pogorelov). Away from the boundary, this inequality controls the size of the derivative ... Read more


UBC Applied Mathematics Meeting

Adjoint L-value and the Tate conjecture

October 28, 2025 - 10:00 am to 12:00 pm

MATH 202

I will present an idea of how to describe (to some extent conjecturally) the explicit generators of Tate cycles under correspondence action in quaternionic Shimura varieties. Read more

Perfectoid Rings and p-adic L-functions

October 28, 2025 - 10:00 am to 12:00 pm

MATH 202

I will discuss work in progress on the extension of an Iwasawa-style p-adic L-function to a certain kind of function on a perfectoid space. This kind of extension is implicit in work of Colmez, but the applications seem not to have been studied yet. Read more

Cut-and-paste K-theory of manifolds and SK-automorphisms

October 28, 2025 - 1:00 pm to 2:00 pm

Given two manifolds M and N, one can ask whether it is possible to cut M up into pieces and reassemble them to obtain N. This “cut-and-paste” (SK) relation fits into the framework of scissors congruence K-theory, which is an extension of higher algebraic K-theory to more ... Read more
