Dynamical Systems Seminar

Title: Introduction to Poisson suspensions
Speaker: Emmanuel Roy
Speaker Info: University of Paris XIII
Brief Description:
Special Note:

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.

Joint work with Elise Janvresse and Thierry de la Rue.
