Structure of crossed products by strictly proper actions on continuous-trace algebras

Siegfried Echterhoff, Dana P. Williams

We examine the ideal structure of crossed products B\rtimes G where B is a continuous-trace C*-algebra and the induced action of G on the spectrum of B is proper. In particular, we…

Groupoid equivalence and the associated iterated crossed product

Jonathan Henry Brown, Geoff Goehle, Dana P. Williams

Given groupoids $G$ and $H$ and a $(G, H)$ -equivalence $X$ we may form the transformation groupoid $G ⋉ X ⋊ H$ . Given a separable groupoid dynamical system $(A,G\ltimes X\…

Fell bundles and imprimitivity theorems: Mansfield's and Fell's theorems

S. Kaliszewski, Paul S. Muhly, John Quigg +1

In the third and latest paper in this series, we recover the imprimitivity theorems of Mansfield and Fell using our technique of Fell bundles over groupoids. Also, we apply the Rie…
