Serre weight conjectures and modularity lifting for GSp4
Heejong Lee
Abstract
Given a Galois representation attached to a regular algebraic cuspidal automorphic representation, the Hodge--Tate weight of the Galois representation is matched with the weight of the automorphic representation. Serre weight conjectures are mod p analogue of such a correspondence, relating ramification at p of a mod p Galois representation and Serre weights of mod p algebraic automorphic forms. In this talk, I will discuss how to understand Serre weight conjectures and modularity lifting as a relationship between representation theory of finite groups of Lie type (e.g. GSp4(Fp)) and the geometry of p-adic local Galois representations. Then I will explain the proof idea in the case of GSp4. This is based on a joint work with Daniel Le and Bao V. Le Hung.

Compactness tools related to PDEs governing compressible flows.
Professor Didier Bresch
(National Centre for Scientific Research)
Abstract
During this mini-course I will try to present some compactness tools that are encountered in the world of weak nonlinear PDE solutions governing compressible flows.
