摘要
利用锥理论和Mnch不动点定理结合单调迭代技巧,研究了Banach空间中一类二阶非线性脉冲奇异微分方程多点无穷边值问题,获得了正解的存在性定理和正解的迭代序列,改进和推广了某些已知结果.
By using cone theory and the MSnch fixed theorem combined with a monotone iterative technique, we investigate multipoint infinite boundary value problems of second order nonlinear impulsive singular differential equations in Banach spaces and establish the existence theorem of positive solutions and iterative sequence for approximating the positive solutions. The results improve and generalize some existing results.
