摘要
本文运用上下解和不动点定理的方法对一类分数阶积分多点边值问题进行研究,通过对格林公式性质的研究和分析得到了该问题正解的存在性。
This paper applies the methods of upper and lower solutions and the fixed point theorem to the study of multi-point boundary value problems of fractional integral of the same category.Through the research and the analysis of the Green formula properties,the existence of positive solutions to the problems is obtained.
