Mathematics behind perturbative quantisation of gauge theories on curved spacetimes

Kasia Rejzner
(University of York)
Abstract
In this talk I will briefly introduce the framework of perturbative algebraic quantum field theory (pAQFT), which is a mathematically rigorous formulation of perturbative QFT that works on a large class of Lorentzian manifolds (globally hyperbolic ones). Then I will focus on the problem of quantisation of gauge theories, which is performed using the Batalin-Vilkovisky (BV) framework. I will also discuss the connection to the factorization algebras framework of Costello and Gwilliam.
 


 

We're always looking to improve the way things work in the Maths Institute for our students. This term, we've received some very useful student feedback, and have managed to implement some changes to be made going forward, to make your experience here as worthwhile and enjoyable as possible. 

We'll be sending round an end-of-term email with a full list of changes implemented as a result of your feedback, but for now, here's just one example below of a change we've made!
