Title: Introduction to Poisson suspensions
Speaker: Emmanuel Roy
Speaker Info: University of Paris XIII
A Poisson suspension is a canonical construction that allows to associate an infinite measure preserving dynamical system (the base) to a probability preserving one (the suspension). This establishes a dictionary between infinite and finite ergodic theory and moreover, as the finite case is much better known, offers a precious tool to tackle some questions in the infinite case. We will illustrate this with basic examples and more recent results as well, while detailing the construction.Date: Tuesday, October 27, 2015
