Topology Seminar - Yvon Verberne
Title: Constructing pseudo-Anosov homeomorphisms using positive twists
Speaker: Yvon Verberne, University of Toronto
Abstract: Thurston obtained the first construction of pseudo-Anosov homeomorphisms by showing the product of two parabolic elements is pseudo-Anosov. A related construction by Penner involved constructing whole semigroups of pseudo-Anosov maps by taking appropriate compositions of Dehn twists along certain families of curves. In this talk, I will present a new construction of pseudo-Anosov homeomorphisms and discuss some of the unique properties associated to maps obtained by this new construction.
