Ergodic Actions and Spectral Triples
Olivier Gabriel, Martin Grensing
In this article, we give a general construction of spectral triples from certain Lie group actions on unital C*-algebras. If the group G is compact and the action is ergodic, we ac…

Fixed points of compact quantum groups actions on Cuntz algebras
Olivier Gabriel
Given an action of a Compact Quantum Group (CQG) on a finite dimensional Hilbert space, we can construct an action on the associated Cuntz algebra. We study the fixed point algebra…

Exact sequences for locally convex subalgebras of Pimsner algebras with an application to Quantum Heisenberg Manifolds
Olivier Gabriel, Martin Grensing
We prove six-term exact sequences of Pimsner-Voiculescu type for certain subalgebras of the Cuntz-Pimsner algebras. This sequence may, in particular, be applied to smooth subalgebr…
