Title: On pointwise multiple convergence problems
Speaker: Wenbo Sun (The Ohio State University)
Abstract: Multiple convergence problems is a topic that has been widely studied in ergodic theory. These questions usually have interesting applications in combinatorics. While the L2L2 multiple convergence problems is well-understood by now, little is known for the pointwise convergence problems. In this talk, I will discuss about some recent advances in the pointwise convergence problems. This is joint work with Sebastian Donoso.
