On the factoriality of q-deformed Araki-Woods von Neumann algebras

Abstract

The $q$-deformed Araki-Woods von Neumann algebras ${\Gamma }_q({\mathcal{H}}_{\mathbb{R}},U_t{)}^{\prime \prime }$ are factors for all $q\in (-1,1)$ whenever $dim({\mathcal{H}}_{\mathbb{R}})\ge 3$. When $dim({\mathcal{H}}_{\mathbb{R}})=2$ they are factors as well for all $q$ so long as the parameter defining $(U_t)$ is `small' or $1$ $($trivial$)$ as the case may be.
