On the K-theory of graph C*-algebras
Gunther Cornelissen, Oliver Lorscheid, Matilde Marcolli
Abstract
We classify graph C*-algebras, namely, Cuntz-Krieger algebras associated to the Bass-Hashimoto edge incidence operator of a finite graph. This is done by a purely graph theoretical calculation of the K-theory and the position of the unit therein.
