On the K-theory of twisted higher-rank-graph C*-algebras
Alex Kumjian, David Pask, Aidan Sims
We investigate the K-theory of twisted higher-rank-graph algebras by adapting parts of Elliott's computation of the K-theory of the rotation algebras. We show that each 2-cocycle o…
An elementary approach to C*-algebras associated to topological graphs
Hui Li, David Pask, Aidan Sims
We develop notions of a representation of a topological graph E and of a covariant representation of a topological graph E which do not require the machinery of C*-correspondences…
Skew-products of higher-rank graphs and crossed products by semigroups
Ben Maloney, David Pask, Iain Raeburn
We consider a free action of an Ore semigroup on a higher-rank graph, and the induced action by endomorphisms of the -algebra of the graph. We show that the crossed product by…
-algebras of labelled graphs III - -theory computations
Teresa Bates, Toke Meier Carlsen, David Pask
In this paper we give a formula for the -theory of the -algebra of a weakly left-resolving labelled space. This is done by realising the -algebra of a weakly left-reso…
