We give a combinatorial description of a family of 2-graphs which subsumes those described by Pask, Raeburn and Weaver. Each 2-graph we consider has an associated -algebra…

Aperiodicity and cofinality for finitely aligned higher-rank graphs
Peter Lewin, Aidan Sims
We introduce new formulations of aperiodicity and cofinality for finitely aligned higher-rank graphs Λ, and prove that C*(Λ) is simple if and only if Λis aperiodic and cofinal. The…
