摘要 应用锥中的不动点定理研究奇异二阶三点边值问题的正解的存在性· 采用一种构造Green函数的方法为出发点 ,利用分段定义算子的手法讨论更一般的奇异二阶三点边值问题· 得到了一个正解的存在性定理· 其中的非线性项可以是变号的· A fixed point theorem is used to study a singular second order three-point boundary value problem. The problem is more general. Combining the method of constructing Green functions with operators defined piecewise, the existence result of positive solutions to a singular second order three-point boundary value problem is established. The nonlinearity can be allowed to change sign.
