Non-isomorphism of $A^{* n}, 2 \leq n \leq \infty$ , for a non-separable abelian von Neumann algebra $A$

Rémi Boutonnet, Daniel Drimbe, Adrian Ioana +1

We prove that if $A$ is a non-separable abelian tracial von Neuman algebra then its free powers $A^{* n}, 2 \leq n \leq \infty$ , are mutually non-isomorphic and with trivial fundamen…

Maximal amenable MASAs of radial type in the free group factors

Remi Boutonnet, Sorin Popa

We prove that if ${(M_{j}, τ_{j})}_{j \in J}$ are tracial von Neumann algebras, $s_{j} \in M_{j}$ are selfadjoint semicircular elements and $t = (t_{j})_{j}$ is a square summable $J$ -tuple of r…
