摘要
通过改进Bainov等关于脉冲微分系统周期边值问题比较原理的证明方法,构造新的上解,在不需要脉冲I_k(x)关于x的半Lipschitz条件的情况下。
This paper improves the proof for the comparison theory of the periodic boundary value problem for the impulsive differential system, which is given by Bainovs. In this paper, the same theory is obtained by constructing new upper solution function, without the semi-Lipschitz condition.
