Dynamic Asymptotic Dimension: relation to dynamics, topology, coarse geometry, and -algebras
Erik Guentner, Rufus Willett, Guoliang Yu
We introduce dynamic asymptotic dimension, a notion of dimension for actions of discrete groups on locally compact spaces, and more generally for locally compact étale groupoids. W…

A non-amenable groupoid whose maximal and reduced -algebras are the same
Rufus Willett
We construct a locally compact groupoid with the properties in the title. Our example is based closely on constructions used by Higson, Lafforgue, and Skandalis in their work on co…
