Generalized $q$-gaussian von Neumann algebras with coefficients, I: Relative strong solidity

##### Abstract

We define ${\Gamma }_{q}\left(B,S\otimes H\right)$, the generalized $q$-gaussian von Neumann algebras associated to a sequence of symmetric independent copies $\left({\pi }_{j},B,A,D\right)$ and to a subset $1\in S={S}^{\ast }\subset A$ and, under certain assumptions, prove their strong solidity relative to $B$. We provide many examples of strongly solid generalized $q$-gaussian von Neumann algebras. We also obtain nonisomorphism and nonembedability results about some of these von Neumann algebras.
