Title:Smooth pressure and Lyapunov spectra for unimodal maps
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Mike Todd, Porto
Abstract:
This is my joint work Godofredo Iommi. We show that for a transitive (so non-renormalisable) unimodal map f, there is a first order phase transition in the pressure function t \mapsto P(-t\log|Df|) if and only if f is non-Collet Eckmann, but has an acip. In this case the transition is at t=1.
