Subgroups of CAT(0) groups, exotic finiteness properties and non-QI-embeddings into linear groups

Claudio Llosa Isenrich, Konstantinos Tsouvalas

For every positive integer $n$ we construct an example of a subgroup $L < G$ of a linear $CAT (0)$ group $G$ such that $L$ is of finiteness type $F_{n - 1}$ and not $\m…

On regular subgroups of $SL_{3} (R)$

Sami Douba, Konstantinos Tsouvalas

Motivated by a question of M. Kapovich, we show that the $Z^{2}$ subgroups of $SL_{3} (R)$ that are regular in the language of Kapovich--Leeb--Porti, or diver…

On projective Anosov subgroups of symplectic groups

Maria Beatrice Pozzetti, Konstantinos Tsouvalas

We prove that a word hyperbolic group whose Gromov boundary properly contains a $2$ -sphere cannot admit a projective Anosov representation into $Sp_{2 m} (C)$ , $m\i…

Residually finite non linear hyperbolic groups

Nicolas Tholozan, Konstantinos Tsouvalas

We exhibit the first examples of residually finite non-linear Gromov hyperbolic groups. Our examples are constructed as amalgamated products of torsion-free cocompact lattices in t…
