摘要
本文利用微分不等式原理及脉冲微分方程初值问题基本理论研究了n类n阶脉冲微 分方程边值问题,得到了该边值问题解的存在性及解的存在唯一性的新的结果.
In this paper, we use differential inequality principles and the initial value prob- lems theory of impulsive differential equations to study n types boundary value problems for nth order impulsive differential equations. Some of new results for existence and existence-u- niqueness of boundary value problems are obtained.
