We define the concept of a partial translation structure T on a metric space X and we show that there is a natural C*-algebra C*(T) associated with it which is a subalgebra of the…

Jacek Brodzki, Graham A. Niblo, Nick Wright

In this paper we show that if a discrete group $G$ acts properly isometrically on a discrete space $X$ for which the uniform Roe algebra $C_{u}^{*} (X)$ is exact then $G$ is an exact gr…
