Abstract

Let MM be a volume finite non-compact complete hyperbolic nn-manifold with totally geodesic boundary. We show that there exists a polyhedral decomposition of MM such that each cell is either an ideal polyhedron or a partially truncated polyhedron with exactly one truncated face. This result parallels Epstein-Penner's ideal decomposition \cite{EP} for cusped hyperbolic manifolds and Kojima's truncated polyhedron decomposition \cite{Kojima} for compact hyperbolic manifolds with totally geodesic boundary. We take two different approaches to demonstrate the main result in this paper. We also show that the number of polyhedral decompositions of MM is finite.
