Nuclearity of semigroup C*-algebras
Astrid an Huef, Brita Nucinkis, Camila F. Sehnem +1
We study the semigroup C*-algebra of a positive cone P of a weakly quasi-lattice ordered group. That is, P is a subsemigroup of a discrete group G with P\cap P^{-1}=\{e\} and such…
Equilibrium states on higher-rank Toeplitz noncommutative solenoids
Zahra Afsar, Astrid an Huef, Iain Raeburn +1
We consider a family of higher-dimensional noncommutative tori, which are twisted analogues of the algebras of continuous functions on ordinary tori, and their Toeplitz extensions.…
KMS states on the operator algebras of reducible higher-rank graphs
Astrid an Huef, Sooran Kang, Iain Raeburn
We study the equilibrium or KMS states of the Toeplitz C*-algebra of a finite higher-rank graph which is reducible. The Toeplitz algebra carries a gauge action of a higher-dimensio…
Stacey crossed products associated to Exel systems
Astrid an Huef, Iain Raeburn
There are many different crossed products by an endomorphism of a C*-algebra, and constructions by Exel and Stacey have proved particularly useful. Here we show that every Exel cro…
Naturality of Rieffel's Morita equivalence for proper actions
Astrid an Huef, S. Kaliszewski, Iain Raeburn +1
Suppose that a locally compact group acts freely and properly on the right of a locally compact space . Rieffel proved that if is an action of on a -algebra …
