Modeling the Evolution of Cooperation at Multiple Levels of Organization

October 31, 2025

ESB 4133

Natural selection often simultaneously operates across multiple levels of biological organization, with examples of such cross-scale evolutionary dynamics arising in settings including the evolution of the early cell, the evolution of virulence, and the sustainable management of common-pool...

From Snapshots to Dynamics: An Optimal Transport Approach

October 29, 2025

ESB 2012

Many modern datasets capture populations only at isolated time points, leaving us with snapshots rather than continuous trajectories. How can we reconstruct the underlying dynamics from such partial views? In this talk, I will present a series of projects that use entropic optimal transport (EOT... Read more

Some progress on Ricci flow

October 29, 2025

MATH126

In this talk, I will first discuss some results on Ricci flow on compact complex manifolds with positive first Chern class. Those manifolds are also referred as Fano manifolds. Next I will discuss a Laplacian comparison for manifolds with Kato bound on curvature and its applications, in... Read more

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

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

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

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

October 27, 2025

MATH 126

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
