一类时滞微分方程周期边值问题及其最大最小解

Periodic boundary value problems for differential equations with arguments

将上下解方法与单调迭代技巧应用于研究一类时滞微分方程,在正向及反向上下解两种情形下分别讨论了该类方程周期边值问题最大最小解的存在性.

The existence of maximal and minimal solutions for periodic boundary value problems involving nonlinear differential equations with arguments is studied by establishing the new comparison inequalities with lower and upper solutions in both formal and reverse order.
