Homology for higher-rank graphs and twisted C*-algebras
Alex Kumjian, David Pask, Aidan Sims
We introduce a homology theory for k-graphs and explore its fundamental properties. We establish connections with algebraic topology by showing that the homology of a k-graph coinc…

Group actions on labeled graphs and their C*-algebras
Teresa Bates, David Pask, Paulette Willis
We introduce the notion of the action of a group on a labeled graph and the quotient object, also a labeled graph. We define a skew product labeled graph and use it to prove a vers…

Aperiodicity and the primitive ideal space of a row-finite -graph -algebra
Sooran Kang, David Pask
We describe the primitive ideal space of the -algebra of a row-finite -graph with no sources when every ideal is gauge invariant. We characterize which spectral spaces…
