Description
Almost finiteness is an amenability or Rokhlin approximation type condition for group actions or groupoids which has turned out to be closely connected to Z-stability for the corresponding crossed product. Z-stability is one of the central classifiably conditions for nuclear simple separable C*-algebras. We explore a version of the notion of almost finiteness for actions of discrete amenable groups on non-commutative algebras leading to similar results, in particular to Z-stablity of the associated crossed product.
