Feb 14, 2019 at 16:44 comment added Jon Bannon I have, perhaps inelegantly, incorporated the distinction Yemon points out in the body of the question.
Feb 14, 2019 at 14:35 comment added Jon Bannon In fact it is not. In Popa's original preprint only closure was considered without multiplicity. With multiplicity, the first proposed characterization of Gamma holds for all N, even those without Gamma. I am interested in an answer to the question using either notion of weak containment. Thanks Yemon!
Feb 14, 2019 at 14:29 comment added Yemon Choi Jon, are you sure that the definition of weak containment in Popa86 ("weak subequivalence") is the same as the definition of weak containment in your 2nd paragraph?
