PhDYourWay are running a free online webinar, entitled "Is a Maths PhD Right for Me?", sponsored by the London Mathematical Society Inclusion and Diversity Fund, and the Institute of Mathematics and its applications. 

If a PhD seems mysterious, overwhelming, or just plain confusing, this is your chance to get the inside scoop from people who are living it right now. Join a one-hour live Q&A with current Mathematics PhD students from across the UK, who will share their insights about:

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.

The Oxford SIAM Student Chapter are excited to announce their very first joint event with G-Research. Join them for an introductory talk about the company (a great talk to attend if you are keen on internships), followed by an interactive game with the chance to win £100 Amazon vouchers.

Mathematical Institute, C6,  Tuesday 17 February (W5), 3:30 pm. Tea, coffee (decaf available) and biscuits will be provided in the Common Room afterwards.
