Title: Transience in dynamical systems Center for Dynamics and Geometry Seminars Mike Todd, Boston University The statistical behavior of a dynamical system $(X,f)$ can be analyzed using thermodynamic formalism. This usually involves taking some potential $\phi$ and considering the pressure and equilibrium states of $(X,f, \phi)$. Singular behavior of $(X,f)$ can show up in the non-smoothness of the pressure w.r.t. $\phi$. This is referred to as a phase transition'. In the case where $(X,f)$ is a countable Markov shift, Sarig has built a theory relating phase transitions and the notion of transience'. In this talk I'll discuss joint work with G. Iommi, where we study transient phenomena in the compact setting.
