Intrinsic Hutchinson measures and KMS states for iterated function systems with large overlaps
Michael Mampusti, Alexander Mundey, Nicholas Seaton
We study iterated function systems with large overlaps via the Kajiwara-Watatani C*-algebra and its KMS states. Our main contributions are threefold. First, we introduce Markov par…
Twisted operator algebras of self-similar groupoid actions on arbitrary graphs
B. K. Kwaśniewski, A. Mundey
We study self-similar groupoid actions on arbitrary directed graphs together with -valued twists that exhaust the second cohomology group of the associated Zappa-Szép p…
Self-similar groupoid actions on k-graphs, and invariance of K-theory for cocycle homotopies
Alexander Mundey, Aidan Sims
We establish conditions under which an inclusion of finitely aligned left-cancellative small categories induces inclusions of twisted C*-algebras. We also present an example of an…
Morphisms of Cuntz-Pimsner algebras from completely positive maps
Kevin Aguyar Brix, Alexander Mundey, Adam Rennie
We introduce positive correspondences as right C*-modules with left actions given by completely positive maps. Positive correspondences form a semi-category that contains the C*-co…
Splittings for C*-correspondences and strong shift equivalence
Kevin Aguyar Brix, Alexander Mundey, Adam Rennie
We present an extension of the notion of in-splits from symbolic dynamics to topological graphs and, more generally, to C*-correspondences. We demonstrate that in-splits provide ex…
A Cuntz-Pimsner Model for the -algebra of a Graph of Groups
Alexander Mundey, Adam Rennie
We provide a Cuntz-Pimsner model for graph of groups -algebras. This allows us to compute the -theory of a range of examples and show that graph of groups -algebras ca…
C*-algebras associated to graphs of groups
Nathan Brownlowe, Alexander Mundey, David Pask +2
To a large class of graphs of groups we associate a C*-algebra universal for generators and relations. We show that this C*-algebra is stably isomorphic to the crossed product indu…
