Abstract: Right-angled Coxeter groups are finitely generated groups with a very simple presentation, and they arise naturally in geometry. In their context will discuss an algebraic counting problem, which is to estimate the growth of the number of subgroups in terms of the index, and some relations to hyperbolic geometry.
