Volume estimates for right-angled hyperbolic polyhedra
A. Egorov, A. Vesnin
By Andreev theorem acute-angled polyhedra of finite volume in a hyperbolic space are uniquely determined by combinatorics of their 1-skeletons and dihedral angles.…

Ideal right-angled polyhedra in Lobachevsky space
A. Vesnin, A. Egorov
In this paper we consider a class of right-angled polyhedra in three-dimensional Lobachevsky space, all vertices of which lie on the absolute. New upper bounds on volumes in terms…
