$Z$ -graded rings as Cuntz-Pimsner rings

Lisa Orloff Clark, James Fletcher, Roozbeh Hazrat +1

Given a $Z$ -graded ring $A$ and a subring $R \subseteq A$ , it is natural to ask whether $A$ can be realised as the Cuntz-Pimsner ring of some $R$ -system. In this paper, we…

A program for finding all KMS states on the Toeplitz algebra of a higher-rank graph

James Fletcher, Astrid an Huef, Iain Raeburn

The Toeplitz algebra of a finite graph of rank $k$ carries a natural action of the torus $T^{k}$ , and composing with an embedding of $R$ in $T^{k}$ gives…
