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 $M_{q} (H_{R})$ …

A multidimensional solution to additive homological equations

Aleksei F. Ber, Matthijs J. Borst, Sander J. Borst +1

In this paper we prove that for a finite-dimensional real normed space $V$ , every bounded mean zero function $f \in L_{\infty} ([0, 1]; V)$ can be written in the form $f = g \circ T - g$ …

Full proof of Kwapień's theorem on representing bounded mean zero functions on $[0, 1]$

Aleksei F. Ber, Matthijs J. Borst, Fedor A. Sukochev

In [7], Kwapień announced that every mean zero function $f \in L_{\infty} [0, 1]$ can be written as a coboundary $f = g \circ T - g$ for some $g \in L_{\infty} [0, 1]$ and some measure preserv…
