KK-rigidity of simple nuclear C*-algebras

Christopher Schafhauser

It is shown that if $A$ and $B$ are unital separable simple nuclear $Z$ -stable C $^{*}$ -algebras and there is a unital embedding $A \to B$ which is invertible on $K K$ …

AF-Embeddings of Graph Algebras

Christopher Schafhauser

Let $E$ be a countable directed graph. We show that $C^{*} (E)$ is AF-embeddable if and only if no loop in $E$ has an entrance. The proof is constructive and is in the same spirit as…
