Pimsner algebras and Gysin sequences from principal circle actions
Francesca Arici, Jens Kaad, Giovanni Landi
A self Morita equivalence over an algebra B, given by a B-bimodule E, is thought of as a line bundle over B. The corresponding Pimsner algebra O_E is then the total space algebra o…

A twisted spectral triple for quantum SU(2)
Jens Kaad, Roger Senior
We initiate the study of a q-deformed geometry for quantum SU(2). In contrast with the usual properties of a spectral triple, we get that only twisted commutators between algebra e…
