抜粋

We discuss a comparison of the entropy of pseudo-Anosovmaps and the volume of their mapping tori. Recent study of the Weil– Petersson geometry of Teichmüller space tells us that the entropy and volume admit linear inequalities for both directions under some bounded geometry condition. Based on experiments, we present various observations on the relation between minimal entropies and volumes, and on bounding constants for the entropy over the volume from below. We also provide explicit bounding constants for a punctured torus case.
