The structure of KMS weights on étale groupoid C*-algebras.

J Christensen - Journal of Noncommutative Geometry, 2023 - content.ems.press
We generalise a number of classical results from the theory of KMS states to KMS weights in
the setting of C-dynamical systems arising from a continuous groupoid homomorphism c …

KMS states and continuous orbit equivalence for ultragraph shift spaces with sinks

FA Tasca, D Gonçalves - Publicacions matematiques, 2022 - projecteuclid.org

Generalized Gauge Actions on k-graph C∗-Algebras

C Farsi, E Gillaspy, NS Larsen, JA Packer - Indiana University Mathematics …, 2021 - JSTOR
In this paper, we consider non-standard dynamics on the C∗-algebra associated with a
higher-rank graph Λ. These dynamics were first introduced by McNamara in his thesis, and …

KMS states on the crossed product-algebra of a homeomorphism

J Christensen, K Thomsen - Ergodic Theory and Dynamical Systems, 2022 - cambridge.org
Let be a homeomorphism of a compact metric space X. For any continuous function there is
a one-parameter group of automorphisms (or a flow) on the crossed product-algebra defined …
