报告题目:Multiplicity and stability of symmetric closed characteristics on symmetric compact convex hypersurfaces in R^{2n}

报告摘要:It is a classical problem in conservative dynamics to investigate the existence of periodic motions of Hamiltonian systems restricted to energy levels.

Since the global existence result of Rabinowitz and Weinstein in 1978, the problems about multiplicity and stability of closed characteristics on compact convex hypersurfaces in R^{2n}$ have been deeply studied by many mathematicians. In this talk, I will discuss our recent results on these kinds of problems for compact convex hypersurfaces with symmetries.
