    Abstract

    Let F be a surface and suppose that \phi: F -> F is a pseudo-Anosov
    homeomorphism fixing a puncture p of F. The mapping torus M = M_\phi\ is
    hyperbolic and contains a maximal cusp C about the puncture p.

    Abstract

    We show that the automorphism group of the disk complex is isomorphic to the
    handlebody group. Using this, we prove that the outer automorphism group of the
    handlebody group is trivial.
