KMS states on -algebras associated to higher-rank graphs
Astrid an Huef, Marcelo Laca, Iain Raeburn +1
Consider a higher-rank graph of rank k. Both the Cuntz-Krieger algebra and the Toeplitz-Cuntz-Krieger algebra of the graph carry natural gauge actions of the torus T^k, and restric…
KMS states on the C*-algebras of finite graphs
Astrid an Huef, Marcelo Laca, Iain Raeburn +1
We consider a finite directed graph E, and the gauge action on its Toeplitz-Cuntz-Krieger algebra, viewed as an action of R. For inverse temperatures larger than a critical value β…
The primitive ideal space of the C*-algebra of the affine semigroup of algebraic integers
Siegfried Echterhoff, Marcelo Laca
We give a complete description of the primitive ideal space of the C*-algebra associated to the ring of integers R in a number field K as considered in a recent paper by Cuntz, Den…
