唯一性函数和Banach空间含间断项的混合微分-积分方程

Uniqueness Function and Integro differential Equations of Mixed Type with Discontinuous Terms in Banach Spaces

研究了唯一性函数的一些性质，并用单调迭代方法及所得性质研究了Ｂａｎａｃｈ空间中带有不连续项的非线性混合微分－积分方程的广义最小解与最大解存在性问题，并与文献［３～５］中的结果作了比较，推广改造了一些已知结果．

In this paper, we first study some properties for uniqueness function. Then using these properties and monotone interative method we investigate the minimal and maximal solutions of mixed type with discontinuous terms in Banach space. The main theorem in this paper improves and generalizes the related results in .
