The separably acting hyperfinite/amenable II1-factor R has the property that any two embeddings into its own ultrapower are unitarily conjugate. Jung showed in 2009 that the converse holds modulo the Connes Embedding Problem. In this talk we will discuss the recent result that amenability for tracial von Neumann algebras satisfying the Connes Embedding Problem is characterized by the weaker property that any two embeddings into an ultrapower of R are conjugate by unital completely positive maps. Time permitting, we will discuss other recent characterizations of amenability within this context. This is based on joint work with Srivatsav Kunnawalkam Elayavalli.
