MIT Combinatorics Seminar Geometry of Polyhedra Igor Rivin, (Princeton and Temple University) Wednesday, September 14, 2005   4:30 pm    Room 2-142 ABSTRACT We will give a survey of results in the geometry of convex polyhedra in three dimensional Euclidean, hyperbolic, and some other geometries of constant curvature. We will point out some connections with the geometry of surfaces, number theory, and three-dimensional topology.
