摘要
利用M nch不动点定理 ,在较弱的条件下 ,证明了Banach空间二阶非线性混合型脉冲微分—积分方程初值问题解的存在性定理 ,推广并改进了已有结果 .
In this paper, by using the Mnch fixed-point theorem, the existence of solutions of initial value problems for nonlinear second order impulsive integro-differential equations of mixed type in Banach spaces is investigated under the weaker conditions than those in paper [3], and the main results in papers [2, 3] are improved and extended.
