Phase mixing for the Hartree equation and Landau damping in the semiclassical limit

April 24, 2025 - 3:30 pm to 4:30 pm

ESB 4133

This talk focuses on the long-time behaviour of the Hartree equation near translation-invariant steady states, under short-range interaction potentials satisfying the Penrose stability condition. Phase-mixing estimates will be presented, showing decay of the density and ... Read more

Dreams and nightmares about intersection theory

May 6, 2025 - 10:30 am to 11:30 am

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- ... Read more

Jacquet-Rallis transfer for parahoric functions over ramified quadratic extensions

May 6, 2025 - 10:30 am to 11:30 am

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 ... Read more

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

May 6, 2025 - 10:30 am to 11:30 am

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 ... Read more

Fighting the Virus: Disease Modeling and Cybersecurity

May 6, 2025 - 10:30 am to 11:30 am

MATH 203

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 ... Read more

Degeneration technique in Gromov-Witten and Donaldson-Thomas theories

May 6, 2025 - 11:30 am to 12:30 pm

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 ... Read more

Gradient estimates for Stokes equations near curved boundary

May 6, 2025 - 11:30 am to 12:30 pm

MATH 105

We show that the gradient of velocity is bounded in $L^q$ up to the boundary for weak solutions of Stokes equations with Navier BC and curved boundary, whose correctness has already been shown near the flat boundary by us in the previous work [CPAA 2024]. We also prove the ... Read more

Moments of Rankin-Selberg $L$-functions in the prime-power level aspect

May 6, 2025 - 11:30 am to 12:30 pm

MATH 204

In this talk we discuss joint work with Fatma Çiçek on establishing asymptotic formulae with power saving error term for first and second moments of Rankin-Selberg $L$-functions $L(1/2+i\mu,f\otimes g)$ where $f$ varies over newforms of conductor $p^n$ with $p$ being a fixed ... Read more
