The study of the cohomology of line bundles on (partial) flag varieties is an important problem at the intersection of algebraic geometry, commutative algebra, and representation theory. Over fields of characteristic zero, this is well-understood...

In this talk, I'll introduce the Simply Typed Lambda Calculus (STLC), describing how it connects constructive propositional logic and computation. I then discuss how Cartesian Closed Categories serve as models of the STLC, and how the categorical...

UBC Mathematics and the Institute of Applied Mathematics will host an all-day colloquium featuring a series of talks in mathematical biology, bringing together postdoctoral fellows from mathematics and zoology. Tentative Schedule: 9:00 AM - 10:00 AM...

Modular forms are certain holomorphic functions on the upper half-plane that play a central role in number theory. In this talk, I will explain how to relate such functions to the topology of certain manifolds, showing how geometric ideas can be used...

In my talk I am going to present the ways Bowen's method of thermodynamic formalism can be extended and applied to settings other than the one we covered in the seminar last term. In particular, I am going to expand on Bowen's original motivation...

After a brief review of the modular method, in this talk we will explain how hyperelliptic curves have emerged as an important tool in recent years to approach generalized Fermat equations.

The game of Cops and Robbers is a two-player pursuit–evasion game played on a graph, in which a set of cops attempt to capture a single robber. The players occupy vertices and take turns moving along edges; capture occurs when a cop and the robber...

We discuss a differential geometric construction of distinguished holomorphic 2-spheres inside a K3 surface. These 2-spheres degenerate to a line on an affine 3-manifold. The example illustrates a general principle in the SYZ program, where graphs on...

We study semi-discrete variational optimal-transport problems between a continuous source measure and a discrete target measure supported on a 1-d space. We identify discrete nestedness conditions that simplify the matching structure, and propose...
