Subject: S^3 actions From: "Claude Schochet" Date: Tue, 25 Apr 2006 20:05:38 -0400 As long as we are giving general suggestions, I'll throw in S3 equivariant K-theory. There is a spectral sequence (due to Jon Rosenberg and myself, Memoir #348 AMS, 1986 ) relating the ordinary and equivariant K-theory of spaces (and also KK if you are so inclined. ) These work for arbitrary actions - the only requirement is on the group - and S3 is acceptable.
