摘要
We use the saddle point theorem of Benci-Rabinowitz to study the existence of periodic solutions with a fixed energy for second order Hamiltonian conservative systems without any symmetry; the key difficulty of the proof is proving the Palais-Smale condition and the non-constant property for the minimax critical point.
