TITLE: Zhu's trace identity for super vertex algebras

ABSTRACT In 1996, Zhu published an identity involving the trace of representations of vertex algebras. The identity reveals a seeming connection between vertex algebras and modular forms that is little understood. We'll see how this identity can be modified so that it can be applied to super vertex algebras too. Here, modular forms of congruence subfgroups come in to play.
