AF-embeddability of -graph algebras and quasidiagonality of -graph algebras
Lisa Orloff Clark, Astrid an Huef, Aidan Sims
We characterise quasidiagonality of the -algebra of a cofinal -graph in terms of an algebraic condition involving the coordinate matrices of the graph. This result covers a…
Purely infinite simple C*-algebras that are principal groupoid C*-algebras
Jonathan H. Brown, Lisa Orloff Clark, Adam Sierakowski +1
From a suitable groupoid G, we show how to construct an amenable principal groupoid whose C*-algebra is a Kirchberg algebra which is KK-equivalent to C*(G). Using this construction…
Phase transitions on the Toeplitz algebras of Baumslag-Solitar semigroups
Lisa Orloff Clark, Astrid an Huef, Iain Raeburn
Spielberg has recently shown that Baumslag-Solitar groups associated to pairs of positive integers are quasi-lattice ordered in the sense of Nica. Thus they have tractable Toeplitz…
