Finite-dimensional approximation properties for uniform Roe algebras
Hiroki Sako
We study property A for metric spaces with bounded geometry introduced by Guoliang Yu. Property A is an amenability-type condition, which is less restrictive than amenability f…

A generalization of expander graphs and local reflexivity of uniform Roe algebras
Hiroki Sako
We introduce a generalization of expander graphs, which is called a weak expander sequence. It is proved that a uniform Roe algebra of a weak expander sequence is not locally refle…
