Title: Right-angled Coxeter groups and acute triangulations
Abstract: A triangulation of yields a right-angled Coxeter group whose
defining graph is the one-skeleton of that triangulation. In this
case, the Coxeter group is the orbifold-fundamental group of a
reflection orbifold which is finitely covered by a 3-manifold. We
investigate the relationship between acute triangulations of and
the geometry of the associated right-angled Coxeter group.
This is joint work in progress with Sam Kim.
