Title: Positive metric entropy in almost integrable Hamiltonian systems
Speaker: Dong Chen (The Ohio State University)
Abstract: In 1950s Kolmogorov asked the following question, which is closely related to the celebrated KAM theory: Can a non-degenerate nearly integrable Hamiltonian system have positive Kolmogorov-Sinai entropy (a.k.a. metric entropy)? In the talk I will give an introduction to the background of this problem as well as some results we get.
Note: The goal of Welcome Seminar is to give an opportunity to new postdoctoral fellows and tenure track professors to introduce themselves to their colleagues. The talks are intended to be non-technical and accessible to graduate students as well. Please plan to attend and encourage your graduate students to do so as well. The talk will be preceded by a colloquium-style reception at 4:00, in the area adjacent to Cockins Hall 240 on the second floor of the Math Building.
