Volume estimates for right-angled hyperbolic polyhedra

Abstract

By Andreev theorem acute-angled polyhedra of finite volume in a hyperbolic space H 3 are uniquely determined by combinatorics of their 1-skeletons and dihedral angles. For a class of compact rightangled polyhedra and a class of ideal right-angled polyhedra estimates of volumes in terms of the number of vertices were obtained by Atkinson in 2009. In the present paper upper estimates for both classes are improved.2010 Mathematics Subject Classification. 52B10. Key words and phrases. right-angled polyhedron, ideal polyhedron, hyperbolic volume.
