Computing K-theory and Ext for graph C*-algebras
D. Drinen, M. Tomforde
K-theory and Ext are computed for the C*-algebra C*(E) of any countable directed graph E. The results generalize the K-theory computations of Raeburn and Szymanski and the Ext comp…

Viewing AF-algebras as graph algebras
D. Drinen
Every AF-algebra arises as a graph algebra in the sense of Kumjian, Pask, Raeburn, and Renault. For AF-algebras, the diagonal subalgebra defined by Stratila and Voiculescu is consi…
