Résumé
We study finite von Neumann algebras M that admit an approximate identity made with completely positive normal maps whose extention to L-2(M) are compact operators. We prove heredity results, and we state sufficient conditions on actions of countable groups to ensure that the crossed product algebras have the same property.
