摘要
利用推广的锥拉伸与锥压缩不动点定理和Banach空间中的锥理论,在多点边值条件下得到了一类高阶奇异非线性共轭边值问题正解的存在性结果,改进了运用迭代法、锥上不动点定理得出此类问题正解的方法.
By means of the extended fixed point theorem concerning cone compression and expansion and cone theory in Banach space,the existence was obtained in the paper for the singular higher order nonlinear conjugate boundary value problems,subject to multi-point boundary value conditions.The results improved those in known literatures.
