摘要
本文利用脉冲奇异混合边值问题的上下解方法给出了带脉冲的正指数 Emden-fowler 方程次线性奇异混合边值问题正解存在的充分必要条件。
In this paper, a necessary and sufficient condition for the existence of positive solutions to the sublinear singular mixed boundary value problems of Emden--Fowler equations with impulse is given using the method of lower and upper solutions to the impulsive singular mixed boundary value problems.
