Seminar on Tuesday, March 20: Genevieve Walsh

This Tuesday at 5:00, the seminar hosts Genevieve Walsh of Tufts University.

Title: Right-angled Coxeter groups and acute triangulations

Abstract: A triangulation of S^2 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 S^2 and
the geometry of the associated right-angled Coxeter group.

This is joint work in progress with Sam Kim.
