Dimensional reduction and the equivariant Chern character

##### Abstract

We propose a dimensional reduction procedure for $1|1$–dimensional supersymmetric euclidean field theories (EFTs) in the sense of Stolz and Teichner. Our construction is well suited in the presence of a finite gauge group or, more generally, for field theories over an orbifold. As an illustration, we give a geometric interpretation of the Chern character for manifolds with an action by a finite group.
