摘要 运用广义凹算子的不动点定理和格林函数的相关性质,得到一类非线性分数阶微分方程m点边值问题正解的存在唯一性,并构造一个迭代序列去逼近这个正解. Based on the fixed point theorem of the generalized concave operator and the related properties of Green’s function,the existence and uniqueness of positive solutions of m-point boundary value problems of a class of nonlinear fractional differential equations are obtained,and an iterative sequence is constructed to ap-proximate the positive solutions.
