Covariant representations of Hecke algebras and imprimitivity for crossed products by homogeneous spaces

Astrid an Huef, S. Kaliszewski, Iain Raeburn

For discrete Hecke pairs $(G, H)$ , we introduce a notion of covariant representation which reduces in the case where $H$ is normal to the usual definition of covariance for the acti…

Strength of convergence in the orbit space of a transformation group

Robert Archbold, Astrid an Huef

Let (G, X) be a second-countable transformation group with G acting freely on X. It is shown that measure-theoretic accumulation of the action and topological strength of convergen…

Extension problems for representations of crossed-product C*-algebras

Astrid an Huef, S. Kaliszewski, Iain Raeburn +1

We consider the following problem. Suppose $α$ is an action of a locally compact group $G$ on a $C^{*}$ -algebra $A$ , $H$ is a closed subgroup of $G$ , and $(π, U)$ is a covariant repre…
