Title: Recent progress on a question of Katznelson concerning topological recurrence

Speaker: Daniel Glasscock (UMass Lowell)

Speaker's URL: https://www.uml.edu/Sciences/mathematics/faculty/Glasscock-Daniel.aspx

Abstract: Katznelson’s question is a longstanding open question at the intersection of topological dynamics, combinatorial number theory, and harmonic analysis: Is every set of Bohr recurrence a set of topological recurrence? Equivalently, does the set of differences A-A of a set of integers A with bounded gaps contain the iterated difference set (B-B)-(B-B) of a set B of positive upper density? In this talk, I will survey what little is known about Katznelson’s question and explain some recent progress achieved in joint work with Andreas Koutsogiannis and Florian Richter.
