Bundle gerbes on supermanifolds

Differential Geometry 2021-07-07 v2

Abstract

We show that every bundle gerbe on a supermanifold decomposes into a bundle gerbe over the underlying manifold and a 2-form on the supermanifold. This decomposition is not canonical, but is determined by the choice of a projection map to the underlying manifold. Along the way, we prove the familiar cohomological classification theorems for bundle gerbes and bundle gerbes with connection in the context of supermanifolds.
