研究了Riemann-Liouville分数阶微分方程边值问题存在惟一解的充分必要条件。得到了边值问题正解的存在性和惟一性,且构造了迭代序列。
The necessary and sufficient conditions for existence of unique solution for Riemann-Liouville fractional dif-ferential equations are studied.The results can not only involve the existence and uniqueness of positive solutions for boundary value problems, but also be applied to construct an iterative scheme.
