Abstract

By adapting an ultraproduct technique of Junge and Zeng, we prove that radial completely bounded multipliers on qq-Gaussian algebras transfer to qq-Araki-Woods algebras. As a consequence, we establish the ww^{\ast}-complete metric approximation property for all qq-Araki-Woods algebras. We apply the latter result to show that the canonical ultraweakly dense C^\ast-subalgebras of qq-Araki-Woods algebras are always QWEP.
