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

October 28, 2025

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 general settings. In... Read more

Adjoint L-value and the Tate conjecture

October 28, 2025

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

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

The twisted Hodge numbers of the Quot schemes of zero dimensional quotients over curves

October 27, 2025

We study Quot schemes of rank 0 quotients on smooth projective curves. These Quot schemes exhibit a rich and highly structured geometry, with formal analogies to the Hilbert scheme of points on surfaces. In this talk, I will explain a formula for the twisted Hodge groups of the Quot scheme with... Read more

A random walk approach to high-dimensional critical phenomena

October 22, 2025

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 universal behaviour of the... Read more

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

October 22, 2025

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 to explore the... Read more
