The witten genus and equivariant elliptic cohomology

Research output: Contribution to journalArticle

Abstract

We construct a Thom class in complex equivariant elliptic cohomology extending the equivariant Witten genus. This gives a new proof of the rigidity of the Witten genus, which exhibits a close relationship to recent work on non-equivariant orientations of elliptic spectra.
