Super unitary representations revisited

Abstract

With the usual definition of a super Hilbert space and a super unitary representation, it is easy to show that there are lots of super Lie groups for which the left-regular representation is not super unitary. I will argue that weakening the definition of a super Hilbert space (by allowing the super scalar product to be non-homogeneous, not just even) will allow the left-regular representation of all (connected) super Lie groups to be super unitary (with an adapted definition). Along the way I will introduce a (super) metric on a supermanifold that will allow me to define super and non-super scalar products on function spaces and I will show that the former are intimately related to the Hodge-star operation and the Fermionic Fourier transform. The latter also allows me to decompose certain super unitary representations as a direct integral over odd parameters of a family of super unitary representations depending on these odd parameters.
