摘要:

利用临界点理论研究一类非自治二阶Hamilton系统周期解的存在性. 在非线性项F=F1+F2分别满足一定有界性条件的情况下, 根据最小作用原理和极小极大化方法, 得到了若干新的周期解存在定理.

关键词: 哈密顿系统, 周期解, 鞍点定理, 最小作用原理, (PS)条件

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
