This paper investigates special conditions under which the tensor product of two von Neumann algebras will be non-isomorphic to the tensor product of two others. The main tools are the algebraic invariants property Λx (x ≧ 0) (first defined by Powers [18]) and the r ∞ and ρ sets (defined by Araki and Woods [3]).
