Correspondences between graph C*-algebras

Rasmus Bentmann, Ralf Meyer

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 isomo…

Extensions of Cuntz-Krieger algebras

Rasmus Bentmann

We show that a C*-algebra "looking like" a Cuntz-Krieger algebra is a Cuntz-Krieger algebra. This implies that, in an appropriate sense, the class of Cuntz-Krieger algebras is clos…

Cuntz Splice invariance for purely infinite graph algebras

Rasmus Bentmann

We show that the Cuntz Splice preserves the stable isomorphism class of a purely infinite graph C*-algebra with finitely many ideals.

A more general method to classify up to equivariant KK-equivalence

Rasmus Bentmann, Ralf Meyer

Using a homological invariant together with an obstruction class in a certain Ext^2-group, we may classify objects in triangulated categories that have projective resolutions of le…

The K-theoretical range of Cuntz-Krieger algebras

Sara E. Arklint, Rasmus Bentmann, Takeshi Katsura

We augment Restorff's classification of purely infinite Cuntz-Krieger algebras by describing the range of his invariant on purely infinite Cuntz-Krieger algebras. We also describe…

Classification of certain continuous fields of Kirchberg algebras

Rasmus Bentmann

We show that the K-theory cosheaf is a complete invariant for separable continuous fields with vanishing boundary maps over a finite-dimensional compact metrizable topological spac…
