Unital positive Schur multipliers on $S_{n}^{p}$ with a completely isometric dilation

Charles Duquet

Let $1 < p \neq = 2 < \infty$ and let $S_{n}^{p}$ be the associated Schatten von Neumann class over $n \times n$ matrices. We prove new characterizations of unital positive Schur multipliers $…

A characterization of absolutely dilatable Schur multipliers

Charles Duquet, Christian Le Merdy

Let $M$ be a von Neumann algebra equipped with a normal semi-finite faithful trace (nsf trace in short) and let $T : M \to M$ be a contraction. We say that $T$ is absolutely dil…
