On modular semifinite index theory
Jens Kaad
We propose a definition of a modular spectral triple which covers existing examples arising from KMS-states, Podles sphere and quantum SU(2). The definition also incorporates the n…
Spectral flow and the unbounded Kasparov product
Jens Kaad, Matthias Lesch
We present a fairly general construction of unbounded representatives for the interior Kasparov product. As a main tool we develop a theory of C^1-connections on operator * modules…
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…
A local global principle for regular operators in Hilbert C*-modules
Jens Kaad, Matthias Lesch
Hilbert C*-modules are the analogues of Hilbert spaces where a C*-algebra plays the role of the scalar field. With the advent of Kasparov's celebrated KK-theory they became a stand…
