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…

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…
