Overcompleteness of coherent frames for unimodular amenable groups
Martijn Caspers, Jordy Timo van Velthoven
This paper concerns the overcompleteness of coherent frames for unimodular amenable groups. It is shown that for coherent frames associated with a localized vector a set of positiv…
Relative Haagerup property for arbitrary von Neumann algebras
Martijn Caspers, Mario Klisse, Adam Skalski +2
We introduce the relative Haagerup approximation property for a unital, expected inclusion of arbitrary von Neumann algebras and show that if the smaller algebra is finite then the…
Riesz transforms on compact quantum groups and strong solidity
Martijn Caspers
One of the main aims of this paper is to give a large class of strongly solid compact quantum groups. We do this by using quantum Markov semi-groups (QMS's) and non-commutative Rie…
On C*-completions of discrete quantum group rings
Martijn Caspers, Adam Skalski
We discuss just infiniteness of C*-algebras associated to discrete quantum groups and relate it to the C*-uniqueness of the quantum groups in question, i.e. to the uniqueness of a…
Connes embeddability of graph products
Martijn Caspers
We prove that the Connes embedding problem is stable under graph products.
Graph products of operator algebras
Martijn Caspers, Pierre Fima
Graph products for groups were defined by Green in her thesis as a generalization of both Cartesian and free products. In this paper we define the corresponding graph product for r…
