n阶微分方程二点及三点边值问题解的存在性

Existence of solutions for nolinear two and three point boundary value problems of nth-order differentical equation

利用格林函数 ,Schauder不动点定理及上下解方法讨论了n阶非线性常微分方程具有全非线性二点和三点边界条件的边值问题解的存在性 ,并得到了新的结果 .

This paper study existence of solutions of two and three point boundary value problems for nth-order differential equation, using Green's functions, Schauder's fixed point theorem and the methods of upper and lower solutions.
