Geometric classification of isomorphism of unital graph C*-algebras
Sara E. Arklint, Søren Eilers, Efren Ruiz
We geometrically describe the relation induced on a set of graphs by isomorphism of their associated graph C*-algebras as the smallest equivalence relation generated by five types…

Fredholm modules over graph C*-algebras
Tyrone Crisp
We present two applications of explicit formulas, due to Cuntz and Krieger, for computations in K-homology of graph C*-algebras. We prove that every K-homology class for such an al…

Quasitraces on exact C*-algebras are traces
Uffe Haagerup
It is shown that all 2-quasitraces on a unital exact C*-algebra are traces. As consequences one gets: (1) Every stably finite exact unital C*-algebra has a tracial state, and (2) i…
