一类二阶隐式微分方程三点边值问题解的存在性

Solution Existence of Second Order Implicit Differential Equation with Three-point Boundary Value Problems

讨论一类二阶隐式微分方程三点边值问题解的存在性,利用上下解方法和单调迭代技巧,获得了至少存在两个解的充分条件.

The solution existence of second order implicit differential equation with three-point boundary value problems was studied in this paper.By using upper and lower solution method and monotone iterative techniques,an result about the existence of at least two solutions was obtained.
