摘要
本文利用含间断项增算子不动点定理讨论了一类非线性Volterra型积分方程正解存在唯一性.在解存在性准则中取消了函数连续性限制,在较弱条件下得到了正解存在唯一性定理.
In this paper, the fixed point theorem of increasing operator with noncontinuity is utilized to discuss the existence and uniqueness of positive solutionfor a class of non-linear Volterra integral equations. An important conditionof continuity can be replaced by weak condition.
