Analyzing the Weyl construction for dynamical Cartan subalgebras

A. Duwenig, E. Gillaspy, R. Norton

When the reduced twisted $C^{*}$ -algebra $C_{r}^{*} (G, c)$ of a non-principal groupoid $G$ admits a Cartan subalgebra, Renault's work on Cartan subalgebras implies th…

Zappa-Szép product of a Fell bundle and a groupoid

Anna Duwenig, Boyu Li

We define the Zappa-Szép product of a Fell bundle by a groupoid, which turns out to be a Fell bundle over the Zappa-Szép product of the underlying groupoids. Under certain assumpti…

Cartan subalgebras for non-principal twisted groupoid $C^{*}$ -algebras

Anna Duwenig, Elizabeth Gillaspy, Rachael Norton +2

Renault proved in 2008 that if $G$ is a topologically principal groupoid, then $C_{0} (G^{(0)})$ is a Cartan subalgebra in $C_{r}^{*} (G, Σ)$ for any twist $Σ$ over $G$ . However, there are…
