摘　　要：该文研究了一类带有p-Laplacian算子并且非线性项f中含有分数阶导数项以及边界条件中含有非线性积分项的分数阶边值问题唯一正解的存在性.通过构造适当的辅助边值问题和锥上的等价类,利用锥理论与和算子方法获得了该边值问题唯一正解存在的充分条件,建立了一致收敛于唯一正解的单调迭代格式,最后给出了一个具体的例子作为所获结论的应用.This paper investigates the existence of unique positive solution for a class of fractional boundary value problems involving the p-Laplacian operator,a fractional derivative term in the nonlinearity f and nonlinear integral terms in the boundary conditions.By constructing appropriate auxiliary boundary value problems and equivalence classes on cone,and using the theory of cone and the method of sum operators,some sufficient conditions for the existence of unique positive solution are obtained,in addition,a monotone iterative sequence uniformly converging to the unique positive solution is constructed.Finally,an example is given to illustrate the main result.
