摘要
笔者利用Schauder不动点定理、上下解方法和单调迭代技巧，证明了后滞微分方程最大、最小解的存在性，改进和推广了已有的结果．
By using the Schauder fixed point theorem, upper and lower solution＇s method and montone iterative technique, we prove the existence of maximum and minimum solutions of differential equations with delay. The results are extentions of corresponding results for differential equations with delay.
