Simplicity of $*$ -algebras of non-Hausdorff $Z_{2}$ -multispinal groupoids

C. Farsi, N. S. Larsen, J. Packer +1

We study simplicity of $C^{*}$ -algebras arising from self-similar groups of $Z_{2}$ -multispinal type, a generalization of the Grigorchuk case whose simplicity was first proved…

Spectral Triples on noncommutative solenoids from the standard spectral triples on quantum tori

Carla Farsi, Frederic Latremoliere, Judith Packer

We address the natural question: as noncommutative solenoids are inductive limits of quantum tori, do the standard spectral triples on quantum tori converge to some spectral triple…
