Simplicity criteria for etale groupoid -algebras
Danny Crytser, Gabriel Nagy
We develop a framework suitable for obtaining simplicity criteria for reduced -algebras of Hausdorff etale groupoids. This is based on the study of certain non-degenerate $C^*…
Traces arising from regular inclusions
Danny Crytser, Gabriel Nagy
We study the problem of extending a state on an abelian - subalgebra to a tracial state on the ambient -algebra. We propose an approach that is well-suited to the case of…
Continous-trace -graph -algebras
Danny Crytser
A characterization is given for directed graphs that yield graph -algebras with continuous trace. This is established for row-finite graphs with no sources first using a group…
Containment: A Variation of Cops and Robbers
Danny Crytser, Natasha Komarov, John Mackey
We consider "Containment": a variation of the graph pursuit game of Cops and Robber in which cops move from edge to adjacent edge, the robber moves from vertex to adjacent vertex (…
