Operator Algebras 2021-12-07 v3

Abstract

In this paper we study conditions under which, for an inclusion of finite von Neumann algebras NMN \subseteq M, we have the reduced amalgamated free product NM\ast_N M is embeddable into (RˉN1)ω(R \bar{\otimes} N_1)^\omega for some other finite von Neumann algebra N1N_1, where RR is the hyperfinite II1\textrm{II}_1 factor.
