Abstract:
In ergodic theory, correlation sequences are well understood, but little is known about higher order correlations. In this talk, we give an overview of some questions about these sequences, with few answers (and most of them negative). This is joint work with Bryna Kra.Date: Sunday, May 1, 2011
