Τίτλος: Joint ergodicity for polynomial ergodic averages with commuting transformations.
Περίληψη: The work of Furstenberg and Bergelson-Leibman on the Szemeredi theorem and its polynomial extension motivated the study of the limiting behaviour of multiple ergodic averages of commuting transformations with polynomial iterates. Following important work by several mathematicians, their norm convergence was established in full generality by Walsh. But little was known about their limit, even in the seemingly simple cases of two commuting weakly mixing transformations with linearly independent polynomial iterates. I will discuss joint work with B. Kuca in which we rectify the situation somewhat and answer several natural open problems.
