Mathematics Colloquia and Seminars

A vertex algebra is the chiral algebra of a two-dimensional conformal field theory and appears in many exciting problems. W-algebras are the broadest class of these and they are associated to certain data of Lie superalgebras. These W-algebras and their representation categories appear as invariants of 4-dimensional gauge theories and dualities of physics translate into isomorphisms of vertex algebras and equivalences of representation categories of these algebras.
I aim to give an overview of the current understanding of the topic.
