摘要:
利用锥拉伸与压缩不动点定理讨论了一类奇异半正二阶微分方程的三点边值问题，得到了正解存在的一个充分条件，并且给出了正解存在的范围。
Abstract:
Using the Krasnoselskii’s fixed point theorem on compression and expansion of cone, this paper investigates a class of second-order singular semipositone differential equations with three-point boundary value problems; a sufficient and the existent range of positive solutions are given.
