Torsion-free subgroups in arbitrary lattices
If the Lie group $G$ is linear (that is, it has a faithful finite-dimensional linear representation), then $\Gamma$ contains a torsion-free subgroup of finite index (Selberg's lemma). … I am interested in examples of uniform lattices Γ in simply connected semi-simple Lie groups G that Γ have no torsion-free finite index subgroups. Are there any known examples of this type? …
