摘要
本文用李雅普诺夫函数法和 Brouwer 不动点定理究研某些高维非线性周期系统的周期解问题,得到了一些存在唯一稳定周期解的充分条件。
In this paper,by using the method of Lyapunov function and making use of the Brouwer’s fixed point theory,We study the problem of periodic solution for the higher order nonlinear periodical system.We obtain some sufficient conditions which guaranntee the existence,uniqu- eness and stability of periodic solution.
