Stable rank of graph algebras. Type I graph algebras and their limits
Klaus Deicke, Jeong Hee Hong, Wojciech Szymanski
For an arbitrary countable directed graph E we show that the only possible values of the stable rank of the associated Cuntz-Krieger algebra C*(E) are 1, 2 or \infty. Explicit crit…

Coverings of Directed Graphs and Crossed Products of C*-algebras by Coactions of Homogeneous Spaces
Klaus Deicke, David Pask, Iain Raeburn
The graph C*-algebra of a directed graph E is the universal C*-algebra generated by a family of partial isometries satisfying relations which reflect the path structure of E. In th…
