Topological complexity of graph braid group

May 6, 2025

MATH 104

Graph braid group are the fundamental groups of configuration spaces of particles in a graph. Topological complexity is the measure of discontinuity of the motion planning problem. In this talk I will discuss those notions. I will also describe a nonpositively curved cube complex associated to... Read more

Degeneration technique in Gromov-Witten and Donaldson-Thomas theories

May 6, 2025

MATH 104

I will review some aspects of degeneration technique in curve counting problems via Gromov-Witten and Donaldson-Thomas theories. This has been one of the major tools in developments in both theories and computing the invariants. I will then talk about a progress on the foundation of the... Read more

On problems of regularity and existence for critical drift elliptic equations and systems

May 6, 2025

MATH 105

We prove the existence, uniqueness and regularity of weak solutions to the Dirichlet problem for an elliptic equation with a drift b and related result for L^q gradient estimates for perturbed Stokes system. We assume b belongs to weak Morrey class which includes in the 3D case, in particular,... Read more

Fighting the Virus: Disease Modeling and Cybersecurity

May 6, 2025

MATX 1100

Many of the words that we use to describe biological disease are often also used to describe cyber systems (e.g. virus, infected). The overall goal of my research in this area is to see how far we can push this metaphor and what we can learn about cyber systems by using models from the... Read more

Jacquet-Rallis transfer for parahoric functions over ramified quadratic extensions

May 6, 2025

MATH 204

The Gan-Gross-Prasad conjecture relates special values of certain L-functions to period integrals on classical groups. Jacquet and Rallis proposed an approach through the relative trace formula, reducing the problem to two conjectures: a fundamental lemma conjecture and a smooth transfer... Read more

Dreams and nightmares about intersection theory

May 6, 2025

MATH 104

Intersection theory studies the Chow ring, an algebraic structure whose elements correspond to subvarieties of a variety X, with the ring product reflecting the intersection of subvarieties in X. Thanks to the foundational work of Fulton and MacPherson, this theory is well-understood when X is... Read more

Math-Bio: Modelling parasite evolution under increasing temperatures in vector-borne disease

April 30, 2025

ESB4133

Concern for the impact of climate change on the spread and severity of infectious disease is widespread. For long-term management of global health, we need to consider parasite evolution under such environmentalchange. Vector-borne diseases are likely to be particularly affected bychanging... Read more
