Haar systems, KMS states on von Neumann algebras and $C^{*}$ -algebras on dynamically defined groupoids and Noncommutative Integration

Gilles G. de Castro, Artur O. Lopes, Gabriel Mantovani

We analyse certain Haar systems associated to groupoids obtained by certain natural equivalence relations of dynamical nature on sets like ${1, 2, ..., d}^{Z}$ , $\{1,2,...,d\…

KMS and ground states on ultragraph C*-algebras

Gilles Gonçalves de Castro, Daniel Gonçalves

We describe KMS and ground states arising from a generalized gauge action on ultragraph C*-algebras. We focus on ultragraphs that satisfy Condition~(RFUM), so that we can use the p…
