Positive Solutions of Sigular Sublinear Emden Fowler Boundary Value Problems with Impulse
带脉冲的EmdenFowler方程次线性奇异边值问题的正解

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.
