Exactness of free and amenable groups by the construction of Ozawa kernels
Sarah Campbell
Using properties of their Cayley graphs, specific examples of Ozawa kernels are constructed for both free and amenable groups, thus showing that these groups satisfy Property O. It…

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…
