Title: Polynomial ergodic averages for certain countable ring actions
Speaker: Andreu Ferre Moragues – Nicolaus Copernicus University, Torun, Poland
Abstract: Inspired by a recent result of Frantzikinakis that allows one to establish joint ergodicity of general integer valued sequences, we will take a look at the ring actions setup. I will present new joint ergodicity results for families of independent polynomials when the acting ring is a field of characteristic zero, their corollaries in combinatorics and topological dynamics, and the methods of proof. Based on joint work with Andrew Best.
