Inspired by Sergio in Mathematical Biology, we are making a film about how mathematics is expressed or conceived in different languages. As part of that, we would like speakers of as many different languages as possible to say how a selection of terms are expressed in their native tongue. Literally 60 second work (if you can remember the translation). Please email Dyrol.

The past isn't a foreign country on social media; it's an eternal present.

So we made Josh Bull take his exams all over again.

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.
