关于一类常微分方程组周期解的存在性定理
Existence theorem of periodic solutions for a class of ordinary differential systems
【摘要】 研究一类常微分方程组周期解的存在性.在▽F(t,u(t))是线性的条件下,通过使用最小作用原理获得了一个周期解的存在性定理.
【Abstract】 The purpose of this paper is to study the existence of periodic solutions of the following ordinary differential systems{u&(t)+m~2u(t)=■F(t,u(t)),u(O)-u(T)=u&(O)-u&(T)=O With the nonlinearity ■F(t,u(t))being linear, we obtain one existence theorem by using the least action principle.
