一个二阶方程组周期解的存在唯一性

THE EXISTENCE AND UNIQUENESS OF PERIODIC SOLUTION FOR SECOND ORDER EQUATION SYSTEM

应用构造Liapunov函数的方法,研究一个非线性周期系统,得到了保证该系统存在唯一周期解的一个简明判别准则。

This paper investigates a nonlinear periodic system and obtains a concise judgement principle which ensures the existence, uniqueness of the periodic solution for the system by using the methed of Liapunov function.
