Twisted k-graph algebras associated to Bratteli diagrams
David Pask, Adam Sierakowski, Aidan Sims
Given a system of coverings of k-graphs, we show that the cohomology of the resulting (k+1)-graph is isomorphic to that of any one of the k-graphs in the system. We then consider B…

Thierry Giordano, Adam Sierakowski
In 1955 Dye proved that two von Neumann factors not of type I_2n are isomorphic (via a linear or a conjugate linear *-isomorphism) if and only if their unitary groups are isomorphi…
