Title: Equivariant multiplicities and mirror symmetry for Hilbert schemes
Abstract: The global nilpotent cone of a smooth projective curve is an extremely singular variety; in particular, its irreducible components are not reduced. Multiplicities of so-called very stable components were computed by Hausel-Hitchin, using ideas from mirror symmetry. More curiously, they observed that these numbers can be naturally quantized. I will explain how to…
Title: The Grunwald Problem for solvable groups
Abstract: Let $K$ be a number field. The Grunwald problem for a finite group (scheme) G/K asks what is the closure of the image of $H^1(K,G) \to \prod_{v \in M_K} H^1(K_v,G)$. For a general $G$, there is a Brauer—Manin obstruction to the problem, and this is conjectured to be the only one. In 2017, Harpaz and Wittenberg introduced a technique that managed to give a positive answer (BMO is the…

Abstract: This talk is related to the relative Langlands' program, which aims to extend the classical Langlands' program to spherical varieties. In the classical case, a well-known \emph{trace Paley-Wiener theorem} was given by Bernstein, Deligne and Kazhdan in 1986. It gives a characterization of the functions
$$\pi \mapsto \mathrm{Tr}(\pi(f)),$$
with $G$ a reductive $p$-adic group, and where $\pi$ ranges over isomorphism classes of smooth…
