摘要
利用Leggett-Williams不动点定理建立了n阶m点边值问题三个正解的存在性,推广了低阶多点边值问题正解以及多个正解的存在性结论.
The existence of three positive solutions for an n th-order m-point boundary value problem is established by using Leggett-Williams fixed point theorem,which generalizes some results of positive and multiple positive solutions to the lower order boundary value problems with multipoint.
