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…

Exel's Crossed Product and Relative Cuntz-Pimsner Algebras

Nathan Brownlowe, Iain Raeburn

We consider Exel's new construction of a crossed product of a C*-algebra A by an endomorphism α. We prove that this crossed product is universal for an appropriate family of covari…

Fundamental groupoids of k-graphs

David Pask, John Quigg, Iain Raeburn

k-graphs are higher-rank analogues of directed graphs which were first developed to provide combinatorial models for operator algebras of Cuntz-Krieger type. Here we develop a theo…

Extension problems and non-abelian duality for -algebras

Astrid an Huef, S. Kaliszewski, Iain Raeburn

Suppose that is a closed subgroup of a locally compact group . We show that a unitary representation of is the restriction of a unitary representation of if and…

Subquotients of Hecke C^*-algebras

Nathan Brownlowe, Nadia S. Larsen, Ian F. Putnam +1

The Bost-Connes Hecke C^*-algebra can be regarded as a direct limit of subalgebras involving finite sets of primes. Each of these finite-prime analogues of the Bost-Connes algebra…
