分数阶微分方程;多点边值问题;迭合度;Mawhin连续性定理
近年,关于分数阶微分方程边值问题的理论研究取得了不少成果[1-12],共振条件下分数阶微分方程多点边值问题作为分数阶非局部边值问题的一种特殊情况,也受到了研究者们的重视,越来越多的人运用Mawhin的连续性定理来研究多点边值问题,如文献[6]研究了共振条件如下的分数阶微分方程的多点边值问题:

受此启发,本文研究共振条件如下的序列分数阶微分方程多点边值问题:

1 预备知识
首先介绍一些关于迭合度的基本理论.








2 几个有用的引理


和












因此,
结合引理2,得到下面的引理.
3 解的存在性定理


或者




所以

由式(8),有




通过以上讨论易知满足定理1的条件1)和2),下证定理1的条件3)也是满足的.
