Extension problems for representations of crossed-product C*-algebras
Astrid an Huef, S. Kaliszewski, Iain Raeburn +1
We consider the following problem. Suppose is an action of a locally compact group on a -algebra , is a closed subgroup of , and is a covariant repre…
Tensor products with bounded continuous functions
Dana P. Williams
We study that natural inclusions $C^b(X) \tensor A$ into and into . In particular, excepting trivial cases, both these maps are isomorp…
The Dixmier-Douady Class of Groupoid Crossed Products
Paul S. Muhly, Dana P. Williams
We give a formula for the Dixmier-Douady class of a continuous-trace groupoid crossed product that arises from an action of a locally trivial, proper, principal groupoid on a bundl…
Continuous-Trace Groupoid Crossed Products
Igor Fulman, Paul S. Muhly, Dana P. Williams
Let be a second countable, locally compact groupoid with Haar system, and let be a bundle of -algebras defined over the unit space of on which a…
Central twisted transformation groups and group -algebras of central group extensions
Siegfried Echterhoff, Dana P. Williams
We examine the structure of central twisted transformation group \cs-algebras $C_{0}(X)\rtimes_{\id,u}G$, and apply our results to the group \cs-algebras of central group extension…
A symmetric imprimitivity theorem for commuting proper actions
Astrid an Huef, Iain Raeburn, Dana P. Willimas
We initiate a careful study of a generalized symmetric imprimitivity theory for commuting proper actions of locally compact groups H and K on a C*-algebra.
