A Fixed Point Decomposition of Twisted Equivariant K-Theory

arXiv:2202.05788 · doi:10.1090/proc/16491

Abstract

We present a decomposition of rational twisted $G$ -equivariant K-theory, $G$ a finite group, into cyclic group equivariant K-theory groups of fixed point spaces. This generalises the untwisted decomposition by Atiyah and Segal as well as the decomposition by Adem and Ruan for twists coming from group cocycles.
