本文讨论了一类二阶泛函微分方程边值问题.首先将此问题转化为分段的积分方程,然后利用锥上的不动点定理讨论了其多重正解的存在性,得到了此二阶泛函微分方程存在两个正解的结果.
In this paper, we discuss the boundary value problems for a class of second order functional differential equations. We first transform it into a piecewise integral equation, then apply a fixed point theorem on cones to discuss the existence of its multiple positive solutions. It is proved that the second order functional differential equation exists two positive solutions.
