摘要:

利用Schauder不动点定理研究二阶非自治半正的耦合微分方程组Neumann边值问题正解的存在性. 在扰动项积分值符号同正、 同负和异号的情况下, 分别获得了该奇异耦合微分方程组Neumann边值问题存在正解的条件.

关键词: Neumann边值问题, 奇异耦合方程组, 正解, Schauder不动点定理

Abstract:

Using Schauder’s fixed point theorem, the authors studied Neumann boundary value problems of second order nonautonomous semipositive coupled systems. We established the existence of positive solutions for Neumann boundary value problems of the singular coupled systems under the conditions that the signs of integral disturbance terms are positive, or negative, or different.

Key words: Neumann boundary value problem, singular coupled system, positive solution, Schauder’s fixed point theorem
