Thin right-angled Coxeter groups in some uniform arithmetic lattices

Sami Douba

Using a variant of an unpublished argument due to Agol, we show that an irreducible right-angled Coxeter group on $n \geq 3$ vertices embeds as a thin subgroup of a uniform arith…

Proper CAT(0) actions of unipotent-free linear groups

Sami Douba

Let $Γ$ be a finitely generated group of matrices over $C$ . We construct an isometric action of $Γ$ on a complete CAT(0) space $X$ such that the restriction of this action…

Virtually unipotent curves in some non-NPC graph manifolds

Sami Douba

Let $M$ be a graph manifold containing a single JSJ torus $T$ and whose JSJ blocks are of the form $Σ \times S^{1}$ , where $Σ$ is a compact orientable surface with boundary. We show t…
