Aritmethic lattices of $\SO(1,n)$ and units of group rings
Sheila Chagas, Ãngel del RÃo, Pavel Zalesskii
We establish that standard arithmetic subgroups of a special orthogonal group are conjugacy separable. As an application we deduce this property for unit groups of…

Subgroup Conjugacy Separability in Residually Free Groups
S. C. Chagas, I. Kazachkov
We prove that finitely presented residually free groups are subgroup conjugacy separable. Furthermore, if they are of type , then they are also subgroup conjugacy distin…
