摘要
通过构造特殊的锥,应用锥拉伸和锥压缩不动点理论,研究了无穷区间上的二阶非线性奇异微分系统,得到边值条件为非负常数时正解的存在性定理.
By constructing a special cone and using the fixed point theory of cone expansion and compression, this paper deals with the second-order nonlinear singular differential system on the infinite interval. The existence theorem of positive solution with boundary value condition being nonnegative constant is proved.
