摘要
该文讨论了带脉冲的Emden-Fowler方程次线性奇异Dirichlet边值问题,利用上下解方法得到了该类问题正解存在的充分必要条件.在脉冲的影响下得到了多解的存在性结果.
This paper considers the Dirichlet boundary value problem of the singular sublinear Emden-Fowler equations with impulse. A necessary and sufficient condition for the existence of positive solutions to this problem is obtained by the method of lower and upper solutions. Moreover, under the influence of the impulse, a result on the existence of multiple solutions is also given.
