Title:Finer structure of minimal systems, the Bohr problem and its higher version
Seminar:Working Seminar: Dynamics and its Working Tools
Speaker:Xiandong Ye, University of Science and Technology of China
Abstract:
In this talk first I will explain why the regionally proximal relation of order d is an equivalence relation and why the quotient space is a d-step nilsystem for minimal systems. Then we will discuss the Bohr problem, i.e. if the difference of a syndetic set conatains a Bohr_0 set, and its higher version.
