Abstract

In this paper, we find lower bounds for volumes of hyperbolic 3-manifolds with various topological conditions. Let V3 = 1.01494 denote the volume of a regular ideal simplex in hyperbolic 3-space. As a special case of the main theorem, if a hyperbolic manifold M contains an acylindrical surface S, then Vol(M)>= -2 V3 chi(S). We also show that if beta1(M)>= 2, then Vol(M)>= 4/5 V3.
