Where: Carslaw 275 

Title: Vertex superalgebras from prefactorization algebras 

Abstract: Factorization algebras are a mathematical framework for the observables and
symmetries of quantum field theory developed by Costello and Gwilliam.  Inspired by the
chiral algebras of Beilinson and Drinfeld, an important test case for the formalism was
the construction of vertex algebras from a sufficiently nice class of factorization
algebras on the complex plane, along with specific factorization algebra analogues of
important vertex algebras.  We recount joint ongoing work with Rui Peixoto showing that
this construction can be superized.  In particular, we describe the factorization
algebra analogue of the super Kac-Moody vertex algebra, and touch on the super-Virosoro
algebra if time permits.  

We will not assume any familiarity with vertex algebras or mathematical physics for this
talk.
