Maximal and reduced Roe algebras of coarsely embeddable spaces
Jan Spakula, Rufus Willett
Gong, Wang and Yu introduced a maximal, or universal, version of the Roe C*-algebra associated to a metric space. We study the relationship between this maximal Roe algebra and the…

On Rigidity of Roe algebras
Jan Spakula, Rufus Willett
Roe algebras are C*-algebras built using large-scale (or 'coarse') aspects of a metric space (X,d). In the special case that X=G is a finitely generated group and d is a word metri…

Coarse non-amenability and coarse embeddings
Goulnara Arzhantseva, Erik Guentner, Jan Spakula
We construct the first example of a coarsely non-amenable (= without Guoliang Yu's property A) metric space with bounded geometry which coarsely embeds into a Hilbert space.
