设E是Banach空间,本文给出了C[I,E]空间中增算子不动点的迭代方法.利用该方法讨论了Banach空间中非线性积分-微分方程初值问题解的存在性及其迭代求法.
A new theorem of fixed point and an iterative technique for increasing operators in C[I,E] are obtained,where E is a Banach space. As an application,the existence of solutions and the iterative technique of the initial value problem for nonlinear integro-differential equations in Banach spaces are discussed.
