University of Rome Tor Vergata
Extremal Kähler metrics on modifications

October 2, 2025 - 3:30 pm

ESB 4127

I will present the invariance of extremal Kahler manifolds under a suitable class of bimeromorphic morphisms. Focusing mostly on the cscK (constant scalar curvature Kähler) case, I will show how the main result is obtained as a consequence of a general uniform coercivity ... Read more

Thomas Geisser

Rikkyo University
Brauer groups and Neron-Severi groups of surfaces over finite fields.

October 6, 2025 - 11:00 am to 12:00 pm

MATH 126

For a smooth and proper surface over a finite field, the formula of Artin and Tate relates the behavior of the zeta-function at 1 to other invariants of the surface. We give a version which equates invariants only depending on the Brauer group to invariants only depending on ... Read more

Niall Taggart

Queen's University Belfast
Algebraic models for functor calculus

October 7, 2025 - 1:00 pm to 2:00 pm

There is a striking and useful analogy between equivariant homotopy theory and functor calculus. In the equivariant setting, Greenlees conjectured that the category of rational G-spectra has an algebraic model - meaning it is equivalent to the derived category of an abelian ... Read more

Alex Iosevich

University of Rochester
Restriction theory, signal recovery and applications

October 10, 2025 - 3:00 pm to 4:00 pm

ESB 2012 and Zoom

A classical problem in signal recovery is to determine whether a finite signal can be recovered from its Fourier transform with missing values. This problem has been studied by many authors starting with the seminal papers by Matolsci and Szuks in the 70s and Donoho and Stark ... Read more

A geometric approach to regularity for optimal transport maps

October 24, 2025 - 3:00 pm to 4:00 pm

ESB 2012 and Zoom

The first regularity results for maps optimizing an open class of cost were proved by Ma-Trudinger-Wang (2005) using a key inequality which they introduced (based on a classical strategy of Pogorelov). Away from the boundary, this inequality controls the size of the derivative ... Read more
