Nonsofic wreath products of residually finite groups

Gabor Kun, Andreas Thom

This work builds on the breakthrough of OpenAI in finding the first nonsofic group. We analyze the underlying proof mechanism and find further applications. Let $Γ < G$ be such that…

Mixed identities for simple locally finite groups

Henry Bradford, Kıvanç Ersoy, Jakob Schneider +1

A mixed identity of a group is a nontrivial word with constants that vanishes under every substitution of its variables. We derive lower bounds for the length of mixed identities i…

$L^{2}$ -cohomology and deformations of the left regular representation

Christoph Gamm, Andreas Thom

We study deformations of unitary representations $π : G \to U (H)$ whose coefficients lie in the Hilbert-Schmidt ideal $H S (H) \subset B (H)$ . Interesting applications arise for the…

Sublinear growth of 1-cocycles and uniform convexity

Andreas Thom

Let G be a finitely generated group, let $π : G \to GL (E)$ be a uniformly bounded $c_{0}$ -representation on a superreflexive Banach space $E$ , and let $b : G \to E$ be…
