| Abstract: | In order to explore the existence and uniqueness of monotone operator without compactness, continuity, and any convex conditions fixed points in partially ordered Banach space, the paper uses the monotone iterative method and mathematical induction as well as the properties of the sequence gaps. Then we obtained the new fixed point theorems of it. The results obtained generalize the related conclusion, so that it can be widely applicable scope, Meanwhile the conclusion is applied to solve the problem for Volterra integral equation group. |
