Covariant representations of Hecke algebras and imprimitivity for crossed products by homogeneous spaces
Astrid an Huef, S. Kaliszewski, Iain Raeburn
For discrete Hecke pairs , we introduce a notion of covariant representation which reduces in the case where is normal to the usual definition of covariance for the acti…

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…
