We show that all amenable, minimal actions of a large class of nonamenable countable groups on compact metric spaces have dynamical comparison. This class includes all nonamenable hyperbolic groups, many HNNextensions, nonamenable Baumslag-Solitar groups, a large class of amalgamated free groups, lattices in many Lie groups, Ã2-groups, as well as direct products of the above with arbitrary countable groups. As a consequence, crossed products by amenable, minimal and topologically free actions…

. We introduce the notion of tracial amenability for actions of discrete groups on unital, tracial C ∗ -algebras, as a weakening of amenability where all the relevant approximations are done in the
A countable group is allosteric if it admits a minimal action on a compact space with an ergodic invariant measure, which is topologically free but not essentially free. We prove that if Λ is a
