摘要:

     次线性Emden-Fowler方程两点边值问题在很多文献中用到,但对于该类问题的C[0,1]正解的唯一性还没有研究。本文利用单调迭代方法,对这一问题进行了研究,得出了该类方程两点边值问题的C[0,1]正解是存在且唯一的。

关键词: Emden-Fowler方程, 正解, 唯一性

Abstract:

       Two-point boundary value problem of the sublinear Emden-Fowler equations has been addressed in many literatures, but the uniqueness of the C[0,1] positive solution has not been investigated. We employ monotone iterative method to address such problem and derive the uniqueness of the C[0,1] positive solution of the boundary value problem of such equations.

Key words: Emden-Fowler equations, positive solution, uniqueness
