Title:Regularity of weak KAM and Arnold diffusion in a priori stable system with 3 degrees of freedom
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Chong-Qing Cheng, Nanjing University, China
Abstract:
In the contruction of diffusion orbits, one key point is to establish the transversality for the intersection of stable and unstable sets. It is closely related to the problem of regularity of weak KAM. Once the regulairty is obtained, one can construct diffusion orbits by the variational method based on Mather's theory. In this talk, I shall show how to do it for a class of a priori stable Hamiltonian systems with 3 degrees of freedom.
