Event details
Abstract: The study of Out(Fₙ) involves understanding both its action on Culler-Vogtmann Space, as well as certain normal forms called (relative) train track maps. Due to a result of Bestvina, the Lipschitz metric provides a link between these two approaches. We outline some of the recent results in the area; the isometry group with respect to the metric, a new solution of the conjugacy problem for irreducible automorphisms and some future directions for research.
