Let $q,q'\in(-1,1)$ with $q\neq 0$. Let $(U_t)_{t\in\mathbb R}$ be a group of orthogonal transformations of $\ell^2$, let $\mathsf{H}_{\mathbb R}$ be a finite-dimensional real Hilb…

Type-invariance conjecture. The same type-invariance for radial multipliers that holds for free Araki-Woods factors should hold for all $q$-Araki-Woods algebras.
