Given a hyperbolic 3{manifold M containing an embedded closed geodesic, we estimate the volume of a complete hyperbolic metric on the complement of the geodesic in terms of the geometry of M. As a corollary, we show that the smallest volume orientable hyperbolic 3{manifold has volume >: 32.

Given a hyperbolic manifold M and an embedded tube of radius r about some geodesic, we determine an upper bound on the percentage of the volume of M occupied by the tube.
Line arrangements in ℍ
If M = H 3 /G is a hyperbolic manifold and γ ⊂ M is a simple closed geodesic, then γ lifts to a collection of lines in H 3 acted upon by G. In this paper we show that such a collection of linesExpand

Lower bounds on volumes of hyperbolic Haken 3-manifolds
We prove a volume inequality for 3-manifolds having [C o] metrics ``bent'' along a surface and satisfying certain curvature conditions. The result makes use of Perelman's work on the Ricci flow andExpand
Continuity of the renormalized volume under geometric limits

Dehn filling, volume, and the Jones polynomial
Given a hyperbolic 3–manifold with torus boundary, we bound the change in volume under a Dehn filling where all slopes have length at least 2π. This result is applied to give explicit diagrammaticExpand
