报告摘要:This talk concerns the existence of multiple rotating periodic solutions for 2n dimensional Hamiltonian systems. For the symplectic orthogonal matrix Q, the rotating periodic solution has the form of z(t+T) = Qz(t), which might be periodic, anti-periodic, sub-harmonic or quasi-periodic according to the structure of Q. It is proved that there exist at least n geometrically distinct rotating periodic solutions on a given Q invariant energy surface. In order to prove the results, we introduce a new index on rotating periodic orbits.
