Banach空间混合型微分-积分方程极值解的存在性

Existence of Extremal Solutions of Mixed Type Integro differential Equations in Banach Spaces

在Ｂａｎａｃｈ空间得到了混合型二阶微分－积分方程两点边值问题的极值解，并给出了迭代逼近列。

In this paper, we obtain the extremal solutions of mixed type two point boundary value problems in Banach spaces and give out the successive approximation.
