Aritmethic lattices of $\SO(1,n)$ and units of group rings

Sheila Chagas, Ángel del Río, Pavel Zalesskii

We establish that standard arithmetic subgroups of a special orthogonal group $SO (1, n)$ are conjugacy separable. As an application we deduce this property for unit groups of…

Hyperbolic 3-Manifolds Groups are Subgroup Conjugacy Separable

S. C. Chagas, P. A. Zalesskii

A group $G$ is called subgroup conjugacy separable if for every pair of non-conjugate finitely generated subgroups of $G$ , there exists a finite quotient of $G$ where the images of…

Limit Groups are Subgroup Conjugacy Separable

S. C. Chagas, P. A. Zalesskii

A group $G$ is called subgroup conjugacy separable if for every pair of non-conjugate finitely generated subgroups of $G$ , there exists a finite quotient of $G$ where the images of…

Bianchi groups are conjugacy separable

S. C. Chagas, P. A. Zalesskii

We prove that non-uniform arithmetic lattices of $S L_{2} (C)$ and in particular the Bianchi groups are conjugacy separable. The proof based on recent deep results of Agol, Lo…

The Figure Eight Knot Group is Conjugacy Separable

S. C. Chagas, P. A. Zalesskii

We prove that torsion free subgroups of PGL(2,C) (abstractly) commensurable with the Euclidean Bianchi groups are conjugacy separable. As a consequence we deduce the result stated…
