Hyperbolization of a pseudo-Anosov mapping torus (source code)

= Hyperbolization of a pseudo-Anosov mapping torus
{c}

The interior of the mapping torus of a pseudo-Anosov homeomorphism of a compact surface with boundary admits a complete finite-volume hyperbolic metric. Periodic monodromy instead gives a Seifert fibered mapping torus, while reducible monodromy gives a manifold containing an essential torus.
