Normalized entropy versus volume for pseudo-Anosovs (JAPANESE)
[ Abstract ]
We establish an explicit linear inequality between the normalized entropy of pseudo-Anosov automorphisms and the hyperbolic volume of their mapping tori, based on a recent result by Jean-Marc Schlenker on renormalized volume of quasi-Fuchsian
manifolds. This is a joint work with Greg McShane.
