Adding tails to C*-correspondences
Paul S. Muhly, Mark Tomforde
We describe a method of adding tails to C*-correspondences which generalizes the process used in the study of graph C*-algebras. We show how this technique can be used to extend re…

Stability of C*-algebras associated to graphs
Mark Tomforde
We characterize stability of graph C*-algebras by giving five conditions equivalent to their stability. We also show that if G is a graph with no sources, then C*(G) is stable if a…

The ordered K_0-group of a graph C*-algebra
Mark Tomforde
We calculate the ordered K_0-group of a graph C*-algebra and mention applications of this result to AF-algebras, states on the K_0-group of a graph algebra, and tracial states of g…
