Invariance and the twisted Chern character : a case study
Abstract
We give details of the proof of the remark made in G2 that the Chern characters of the canonical generators on the K homology of the quantum group SUq(2) are not invariant under the natural SUq(2) coaction. Furthermore, the conjecture made in G2 about the nontriviality of the twisted Chern character coming from an odd equivariant spectral triple on SUq(2) is settled in the affirmative.
