Abstract:

The authors studied the existence of  periodic solutions for a class of nonautonomous second order Hamiltonian systemsSome new existence theorems for periodic solutions were obtained via the least action principle and the minimax methods as F=F1+F2 satisfied some boundary conditions.

Key words:  Hamiltonian systems, periodic solution, saddle point theorem, the least action principle, (PS) condition
