摘要
利用锥上的不动点指数定理讨论了一类二阶m点脉冲积一微分方程边值问题多个正解的存在性,推广和包含了一些已知结果.
The author has obtained existence and multiplicity of positive solutions of mpoint boundary value problem for second-order impulsive differential equations by using the fixed-point theoty, Moreover, the result generalize and include some known results .
