摘要
利用混合单调算子不动点定理研究了一维非线性奇异P-Lapace差分方程边值问题,得到P-Lapace差分方程边值问题的存在唯一正解的充要条件.
By mixed monotone method,we study boundary value problems of singular one-Dimension P-Laplacian difference equation.sufficient conditions for existence and uniqueness of positive solutions for nonlinear singular boundary value problems with p-Lapacian difference equation are obtained.
