Strong solidity classification of Coxeter groups
Martín Blufstein, Katherine Goldman, Koichi Oyakawa
We prove the dichotomy that every Coxeter group either has a strongly solid group von Neumann algebra or contains the product of an infinite cyclic group and a free group of rank 2…
Boundary rigidity of systolic and Helly complexes
Martín Blufstein, Jérémie Chalopin, Victor Chepoi
In this article, we prove that finite (weakly) systolic and Helly complexes can be reconstructed from their boundary distances (computed in their 1-skeleta). Furthermore, Helly com…
On the twisted conjugacy problem for large-type Artin groups
Martín Blufstein, Motiejus Valiunas
We show that the twisted conjugacy problem is solvable for large-type Artin groups whose outer automorphism group is finite, generated by graph automorphisms and the global inversi…
Generalized small cancellation conditions, non-positive curvature and diagrammatic reducibility
Martin Axel Blufstein, Elias Gabriel Minian, Iván Sadofschi Costa
We present a metric condition which describes the geometry of classical small cancellation groups and applies also to other known classes of groups such as two-dimensi…
Strictly systolic angled complexes and hyperbolicity of one-relator groups
Martin Axel Blufstein, Elias Gabriel Minian
We introduce the notion of strictly systolic angled complexes. They generalize Januszkiewickz and Świątkowski's -systolic simplicial complexes and also their metric counterparts…
