Exactness from Proper Actions
Jacek Brodzki, Graham A. Niblo, Nick Wright
In this paper we show that if a discrete group acts properly isometrically on a discrete space for which the uniform Roe algebra is exact then is an exact gr…

Hilbert space compression and exactness for discrete groups
Sarah J. Campbell, Graham A. Niblo
We show that the Hilbert space compression of any finite dimensional CAT(0) cube complex is 1 and deduce that any discrete group acting properly, co-compactly on a CAT(0) cube comp…

From wall spaces to CAT(0) cube complexes
I. L. Chatterji, G. A. Niblo
We explain how to adapt a construction of M. Sageev's to construct a proper action on a CAT(0) cube complex starting from a proper action on a wall space, and use this to deduce th…
