Harmonic analysis and BMO-spaces of free Araki-Woods factors

Martijn Caspers

We consider semi-group BMO-spaces associated with arbitrary von Neumann algebras and prove interpolation theorems. This extends results by Junge-Mei for the tracial case. We give e…

Weak type operator Lipschitz and commutator estimates for commuting tuples

Martijn Caspers, Fedor Sukochev, Dmitriy Zanin

Let $f : R^{d} \to R$ be a Lipschitz function. If $B$ is a bounded self-adjoint operator and if ${A_{k}}_{k = 1}^{d}$ are commuting bounded self-adjoint operators such th…
