Arham Farid (MI EDI Officer) will join us to chat about current EDI initiatives and to hear our thoughts about ways EDI can improve in the Maths Institute.

Join us to discuss x+y: A Mathematician’s Manifesto for Rethinking Gender by Eugenia Cheng.

Dr Jenny Power (Heriot-Watt University) will share some of the personal and unexpected lessons she learnt while completing her PhD. We’ll then discuss how a “perfect PhD student” doesn’t exist!

In our first event of term, we have a fun quiz competition to help you get to know other Mathematrix members and a free pizza lunch from White Rabbit! What more could you want?

We give an introduction to a rigorous renormalization group analysis of the sine-Gordon model with a focus on deriving the lowest-order beta function.

The representation theory of Lie algebras over fields of positive characteristic behaves quite differently to the characteristic zero case. For example, in positive characteristic, the dimension of all simple modules is finite and bounded. In this talk, we’ll begin by recalling the classification of finite simple representations of sl_2, and then explore how this changes when we move to the positive characteristic setting. Along the way, we’ll discuss the additional structures that appear in positive characteristic, such as restricted Lie algebras, the p-centre, and reduced enveloping algebras.
