[HTML][HTML] KMS weights on graph C⁎-algebras

K Thomsen - Advances in Mathematics, 2017 - Elsevier
The paper contains a study of the gauge invariant KMS weights for a generalized gauge
action on a graph C⁎-algebra. When the graph is irreducible and has the property that there …

Symmetries of the KMS simplex

J Christensen - Communications in Mathematical Physics, 2018 - Springer
A continuous groupoid homomorphism c on a locally compact second countable Hausdorff
étale groupoid GG gives rise to a C*-dynamical system in which every β β-KMS state can be …

The Toeplitz noncommutative solenoid and its Kubo–Martin–Schwinger states

N Brownlowe, M Hawkins, A Sims - Ergodic Theory and Dynamical …, 2019 - cambridge.org
We use Katsura's topological graphs to define Toeplitz extensions of Latrémolière and
Packer's noncommutative-solenoid-algebras. We identify a natural dynamics on each …

KMS states on the operator algebras of reducible higher-rank graphs

A an Huef, S Kang, I Raeburn - Integral Equations and Operator Theory, 2017 - Springer
We study the equilibrium or KMS states of the Toeplitz C^* C∗-algebra of a finite higher-rank
graph which is reducible. The Toeplitz algebra carries a gauge action of a higher …

KMS states on the -algebras of Fell bundles over {\'e}tale groupoids

RD Holkar, MA Hossain - arXiv preprint arXiv:2309.10354, 2023 - arxiv.org
Let $ p\colon\mathcal {A}\to G $ be a saturated Fell bundle over a locally compact,
Hausdorff, second countable,{\'e} tale groupoid~ $ G $, and let $\mathrm {C}^*(G;\mathcal …

[PDF][PDF] KMS states of graph algebras with a generalised gauge dynamics

R McNamara - 2015 - ourarchive.otago.ac.nz
We start by studying the KMS states of the Toeplitz algebra and graph algebra of a finite
directed graph, each with an a generalised gauge dynamics. We characterise the KMS …

[HTML][HTML] KMS states on the Toeplitz algebras of higher-rank graphs

J Christensen - Journal of Mathematical Analysis and Applications, 2020 - Elsevier
Abstract The Toeplitz algebra TC⁎(Λ) for a finite k-graph Λ is equipped with a continuous
one-parameter group α r for each r∈ R k, obtained by composing the map R∋ t→(eitr 1 …

[HTML][HTML] Constructing KMS states from infinite-dimensional spectral triples

M Goffeng, A Rennie, A Usachev - Journal of Geometry and Physics, 2019 - Elsevier
We construct KMS-states from Li 1-summable semifinite spectral triples and show that in
several important examples the construction coincides with well-known direct constructions …

[HTML][HTML] Preferred traces on C⁎-algebras of self-similar groupoids arising as fixed points

J Claramunt, A Sims - Journal of Mathematical Analysis and Applications, 2018 - Elsevier
Abstract Recent results of Laca, Raeburn, Ramagge and Whittaker show that any self-similar
action of a groupoid on a graph determines a 1-parameter family of self-mappings of the …
