C*-algebras associated to coverings of k-graphs
Alex Kumjian, David Pask, Aidan Sims
A covering of k-graphs (in the sense of Pask-Quigg-Raeburn) induces an embedding of universal C*-algebras. We show how to build a (k+1)-graph whose universal algebra encodes this e…

Ultragraph C*-algebras via topological quivers
Takeshi Katsura, Paul S. Muhly, Aidan Sims +1
Given an ultragraph in the sense of Tomforde, we construct a topological quiver in the sense of Muhly and Tomforde in such a way that the universal C*-algebras associated to the tw…
