Abstract:

We present a new approach and improvements to the recent results of Gabai, Meyerhoff and Milley concerning tubes and short geodesics in hyperbolic $3$-manifolds. We establish the following two facts: if a hyperbolic $3$-manifold admits an embedded tubular neighbourhood of radius $r_0>1.32$ about any closed geodesic, then its volume exceeds that of the Weeks manifold. If the shortest geodesic of $M$ has length less than $\ell _0<0.1$, then its volume also exceeds that of the Weeks manifold.
