Strongly convergent matrix models for -Gaussian algebras
Martijn Caspers, Enli Chen
The paper builds finite‑dimensional random matrix models that strongly converge to finite q‑Gaussian families for |q| < √2 − 1, using graph‑product semicircular elements, ultraprod…
Rigid Graph Products
Matthijs Borst, Martijn Caspers, Enli Chen
We prove rigidity properties for von Neumann algebraic graph products. We introduce the notion of rigid graphs and define a class of II-factors named .…
On the best constants of Schur multipliers of higher order divided difference functions
Martijn Caspers, Jesse Reimann
Let be such that . Let be the th order divided difference. A special case of our m…
Internal graphs of graph products of hyperfinite II-factors
Martijn Caspers, Enli Chen
In this paper, we show that for a graph from a class named H-rigid graphs, its subgraph , named the internal graph of , is an isomorphism invariant of the g…
Higher order perturbation estimates in quasi-Banach Schatten spaces through wavelets
Martijn Caspers, Emiel Huisman
Let . Let and set the Hölder combination . Ass…
On the best constants of Schur multipliers of second order divided difference functions
Martijn Caspers, Jesse Reimann
We give a new proof of the boundedness of bilinear Schur multipliers of second order divided difference functions, as obtained earlier by Potapov, Skripka and Sukochev in their pro…
