Spectral flow invariants and twisted cyclic theory for the Haar state on SUq(2)

Carey, Alan; Rennie, Adam; Tong, K


In [A.L. Carey, J. Phillips, A. Rennie, Twisted cyclic theory and an index theory for the gauge invariant KMS state on Cuntz algebras. arXiv:0801.4605], we presented a K-theoretic approach to finding invariants of algebras with no non-trivial traces. This paper presents a new example that is more typical of the generic situation. This is the case of an algebra that admits only non-faithful traces, namely S Uq (2) and also KMS states. Our main results are index theorems (which calculate spectral...[Show more]
