On the isomorphism class of $q$ -Gaussian W $^{*}$ -algebras for infinite variables

Martijn Caspers

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 t…

Multilinear transference of Fourier and Schur multipliers acting on non-commutative $L_{p}$ -spaces

Martijn Caspers, Amudhan Krishnaswamy-Usha, Gerrit Vos

Let $G$ be a locally compact unimodular group, and let $ϕ$ be some function of $n$ variables on $G$ . To such a $ϕ$ , one can associate a multilinear Fourier multiplier, which acts o…

On the isomorphism class of $q$ -Gaussian C $^{*}$ -algebras for infinite variables

Matthijs Borst, Martijn Caspers, Mario Klisse +1

For a real Hilbert space $H_{R}$ and $- 1 < q < 1$ Bozejko and Speicher introduced the C $^{*}$ -algebra $A_{q} (H_{R})$ and von Neumann algebra $M_{q} (H_{R})$ …

Local and multilinear noncommutative de Leeuw theorems

Martijn Caspers, Bas Janssens, Amudhan Krishnaswamy-Usha +1

Let $Γ < G$ be a discrete subgroup of a locally compact unimodular group $G$ . Let $m \in C_{b} (G)$ be a $p$ -multiplier on $G$ with $1 \leq p < \infty$ and let $T_{m}: L_p(\widehat{G})…
