Let M q (H ℝ ) be the q-Gaussian von Neumann algebra associated with a separable infinite dimensional real Hilbert space H ℝ where -1<q<1. We show that M q (H ℝ )¬≃M 0 (H ℝ ) for -1<q≠0<1. The C * -algebraic counterpart of this result was obtained recently in [1]. Using ideas of Ozawa we show that this non-isomorphism result also holds on the level of von Neumann algebras.
