C*-algebras associated to group actions on trees, and connections to classification
Published 2024We study C*-algebras arising from actions of countable, discrete groups on directed trees. Such an action gives rise to a C*-algebra in two ways: the action induces an action of the group on the boundary of the tree, ...Thesis -
Simplicity of twisted C*-algebras of topological higher-rank graphs
Published 2019-06-30In a recent series of papers, Kumjian, Pask, and Sims have investigated the effect of "twisting" C*-algebras associated to higher-rank graphs using a categorical 2-cocycle on the graph. This work has included a characterisation ...Thesis
