摘要
利用混合单调算子不动点定理,研究了一类非线性分数阶微分方程边值问题正解的存在唯一性.主要结论不仅保证了正解的存在唯一性,而且能够构造一迭代序列去逼近此解.最后,举例说明所得结论的有效性.
In this paper, by using the fixed point theorem for mixed monotone operator, the existence and uniqueness of positive solution to nonlinear fractional differential equation boundary value problems is concerned. Our results can not only guarantee the existence and uniqueness of positive solution, but also be applied to con- struct an iterative scheme for approximating the solution. Finally, the example is given to illustrate the main result.
