CORRESPONDENCES BETWEEN GRAPH C*-ALGEBRAS

Seminarium

North Atlantic Noncommutative Geometry Seminar

---

We describe proper correspondences from graph C*-algebras to arbitrary C*-algebras by K-theoretic data. If the target C*-algebra is a graph C*-algebra as well, we may lift an isomorphism and its inverse on a certain invariant to correspondences back and forth that are inverse to each other up to ideal-preserving homotopy. This implies a classification theorem for purely infinite graph C*-algebras up to stable isomorphism.
