Resumo

The purpose of this minicurse is to introduce the audience to a conjecture by Beilinson and Drinfeld regarding the higher chiral homology groups of the affine Kac-Moody algebra at positive integral level. 

In this second lecture we will relate chiral algebras with more familiar objects from representation theory: infinite dimensional Lie algebras and more generally vertex algebras. We will define and give examples of the vertex algebras associated affine Kac-Moody Lie algebras and state the Beilinson and Drinfeld conjecture.
