Scientific paper

We prove that uniform Roe C*-algebras associated to some expander graphs
coming from discrete groups with property (\tau) are not K-exact. In
particular, we show that this is the case for the expander obtained as Cayley
graphs of a sequence of alternating groups (with appropriately chosen
generating sets).
