POSITIVE SOLUTIONS OF BOUNDARY VALUE PROBLEM FOR A SYSTEM OF NONLINEAR ORDINARY DIFFERENTIAL EQUATIONS
收藏 引用
Annals of Differential Equations 2005年 第2期21卷 153-160页
作者: LiHongyu SunJingxian SchoolofMath.andSystemScience ShandongUniversityJinan250100 Dept.ofMath. XuzhouNormalUniversityXuzhou221116
By using topological method, we study a class of boundary value problem for a system of nonlinear ordinary differential equations. Under suitable conditions, we prove the existence of positive solution of the problem.
