On Amenability and LEF-ness for topological full groups

Xin Ma

In this paper, we prove that for a topologically free distal action $α$ of a countable discrete group $G$ on the Cantor set, the topological full group $[[α]]$ is amenable if and o…

Boundary actions of CAT(0) spaces and their $C^{*}$ -algebras

Xin Ma, Daxun Wang

In this paper, we study boundary actions of CAT(0) spaces from a point of view of topological dynamics and $C^{*}$ -algebras. First, we investigate the actions of right-angled Coexter…
