Two-sided combinatorial volume bounds for non-obtuse hyperbolic polyhedra

Chris Atkinson (Temple University)

Abstract: We give a method for computing upper and lower bounds for the volume of a non-obtuse hyperbolic polyhedron in terms of the combinatorics of the 1-skeleton. We will first describe how to obtain volume bounds in the right-angled case and then show how the more general case follows from techniques related to the proof of Thurston’s Orbifold Theorem and Schlaefli’s formula.
