摘    要:文章的主要目的是研究以下二阶系统{ü(t)+q(t)u·(t)=↓△F(t,u(t))u(0)-u(T)=u·(0)-e^Q(T)u·(T)=0,a.e.t∈0,T]。在F(t,x)=F1(t,x)+F2(x)满足假设(A)及F1(t,x),F2(x)满足一些可解性条件下,通过使用最小作用原理获得了2个新的存在性定理。

关 键 词:周期解  最小作用原理  二阶系统

Abstract:The purpose of this paper is to study the existence of periodic solutions of the following second order systems{ü(t)+q(t)u·(t)=↓△F(t,u(t))u(0)-u(T)=u·(0)-e^Q(T)u·(T)=0,a.e.t∈0,T]When F(t,x)=F1(t,x)+F2(x)satisfies assumption (A) and F1(t,x),F2(x)satisfy many solvability conditions.Some new existence theorems are obtained by the least action principle.
Keywords:periodic solutions  the least action principle  second order systems
