Alexandrov groupoids and the nuclear dimension of twisted groupoid $C^{*}$ -algebras

Kristin Courtney, Anna Duwenig, Magdalena C. Georgescu +2

We consider a twist $E$ over an étale groupoid $G$ . When $G$ is principal, we prove that the nuclear dimension of the reduced twisted groupoid $C^{*}$ -algebra is bounded by…

Imprimitivity theorems and self-similar actions on Fell bundles

Anna Duwenig, Boyu Li

We introduce the notion of self-similar actions of grouopids on other groupoids and Fell bundles. This leads to a new imprimitivity theorem arising from such dynamics, generalizing…

Renault's $j$ -map for Fell bundle $C^{*}$ -algebras

Anna Duwenig, Dana P. Williams, Joel Zimmerman

If $p : B \to G$ is a Fell bundle over an étale groupoid, then we show that there is an norm reducing injective linear map $j \colon C^*_r(G;\mathcal B)\to Γ_{0}(G;\ma…
