摘要
笔者通过构造一个特殊的锥，利用不动点指数理论，讨论了在带参数的积分边界条件下的三阶三点奇异问题多个正解的存在性问题，并在一定条件下得到两个正解的存在性结果．
By constructiong a special cone and using the fixed point index theory,we investigate the existence of positive solutions for third - order three - point singular boundary value problem with integral boundary conditions, and obtain twin positive solutions＇ existence with certain conditions.
