利用Schauder不动点理论和上下解方法,讨论了一类半正奇异二阶微分方程雇Neumann边值条件下受脉冲影响的正解存在性.
The existence results of positive solutions are presented for semipositone second-order Neumann boundary value problems with singular impulsive differential equations. The proof uses Schauder fixed point theorem and upper and lower solutions method.
