Twisted crossed products of Banach algebras

Alonso Delfín, Carla Farsi, Judith Packer

Given a locally compact group $G$ , a nondegenerate Banach algebra $A$ with a contractive approximate identity, a twisted action $(α, σ)$ of $G$ on $A$ , and a family $R$ o…

Twisted Bredon-Illman Cohomology is a Morita Invariant

Carla Farsi, Laura Scull, Jordan Watts

We show that the twisted Bredon-Illman cohomology defined by Mukherjee-Mukherjee applied to compact Lie group action groupoids is Morita-invariant. This cohomology uses coefficient…

Continuity for the spectral propinquity of the Dirac operators associated with an analytic path of Riemannian metrics

Carla Farsi, Frederic Latremoliere

We prove that a polynomial path of Riemannian metrics on a closed spin manifold induces a continuous field in the spectral propinquity of metric spectral triples.

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…
