Structure theory and stable rank for C*-algebras of finite higher-rank graphs

Publication Name

Proceedings of the Edinburgh Mathematical Society


We study the structure and compute the stable rank of-algebras of finite higher-rank graphs. We completely determine the stable rank of the-algebra when the-graph either contains no cycle with an entrance or is cofinal. We also determine exactly which finite, locally convex-graphs yield unital stably finite-algebras. We give several examples to illustrate our results.
