Abstract:

The notion of a factorization algebra was introduced by Beilinson and Drinfeld in their work on conformal field theory and subsequently variants of their notion have been developed for topological and (Euclidean) quantum field theory. In this talk, I’ll introduce the version developed by Kevin Costello and me and I’ll focus on a direct, simple construction of a factorization algebra that recovers the vertex algebra associated to affine Kac-Moody Lie algebras. At the end, I’ll explain how this relates to perturbative QFT.
