Title:Closed orbits of pseudo-Anosov flows: cardinality and length growth
Seminar:Geometry Luncheon Seminar
Speaker:Sergio Fenley, Florida State University
Abstract:
There are Anosov and pseudo-Anosov flows so that some orbitsare freely homotopic to infinitely many other orbits. Given such an infinite free homotopy class we analyse its interaction with the torus decomposition of the manifold: whether they can all be contained in a Seifert piece or atoroidal piece. There is a natural ordering of an infinite subset of such a collection, indexed as (gamma_i). We analyse the growth of the length of gamma_i as a function of i.We obtain some inequalities which have some ergodic theory consequences. This is a joint work with Thomas Barthelme.
