分数阶导数是整数阶导数的推广,主要利用Mawhin的连续性定理及迭合度理论,讨论了共振条件下分数阶微分方程多点边值问题解的存在性,得到了解存在的充分条件,推广了已有的结果.
Fractional order derivative is a derivative of the promotion of integer. This paper discusses the exis tence of solutions for fractional multi-point boundary value problems at resonance by using Mawhin's continu ous theorem and coincidence degree theory and the sufficient conditions for the boundary value problems is ob- tained, generalizing known results.
