Norm convergence of nonconventional ergodic averages
If you have a question about this talk, please contact Ben Green.
Let G be a group of measure preserving transformations of a probability space. The limiting behavior of the nonconventional ergodic averages associated with this action has been the subject of much attention since the work of Furstenberg on Szemerédi’s theorem. We will discuss this problem, and how to establish the convergence of these averages whenever the group is nilpotent and the trajectories are polynomial.
