摘要
给出了一阶常微分方程周期边值问题的拟上下解概念,并得到了最大、最小拟解的存在性以及任一拟解对的单调迭代序列.
The concept of quasi-upper and lower solutions is given for the periodic boundary value problem of one-order ordinary differential equation.The existence of the minimal and maximal quasi-solutions and the monotone iterative sequences of any coupled quasi-solutions are obtained.
