摘要
在有一般化的上下解的条件下 ,研究了一阶混合型积分微分方程的周期边值问题的可解性和最小最大解的存在性· 讨论基于迭合度方法 ,单调迭代方法和新的比较定理·
The existence of at least one solution and the existence of extreme solutions of periodic boundary value problems for first order integrodifferential equations of mixed type are studied,in the presence of generalized upper and lower solutions. The discussion is based on new comparative theorems and coincidence degree and monotone iterative methods.
