MF traces and the Cuntz semigroup

Christopher Schafhauser

A trace $τ$ on a separable C*-algebra $A$ is called matricial field (MF) if there is a trace-preserving morphism from $A$ to $Q_{ω}$ , where $Q_{ω}$ denotes the norm ultrapower of the u…

Traces on Topological Graph Algebras

Christopher Schafhauser

Given a topological graph $E$ , we give a complete description of tracial states on the C*-algebra $C^{*} (E)$ which are invariant under the gauge action; there is an affine h…

Cuntz-Pimsner Algebras, Crossed Products, and $K$ -Theory

Christopher Schafhauser

Suppose $A$ is a $C^{*}$ -algebra and $H$ is a $C^{*}$ -correspondence over $A$ . If $H$ is regular in the sense that the left action of $A$ is faithful and is given by compact operators,…
