DESCRIPTION:The coarse Baum&ndash\;Connes conjecture is a foun
 dational statement connecting coarse K-homology wi
 th K-theory of Roe algebras. It has long been know
 n to be false for certain spaces constructed as in
 finite disjoint unions of expander-like objects. T
 he goal of this talk is to present recent joint wo
 rk with Kitsios and Schick\, in which we prove a c
 onjecture of Roe by showing that even fairly tame 
 Riemannian manifolds (specifically\, certain warpe
 d cones) violate the coarse Baum&ndash\;Connes con
 jecture. In both cases the failure of Baum-Connes 
 relies on some spectral gap type properties of the
  underlying metric spaces.
