摘要: 首先, 用Banach压缩映射原理和Krasnoselskii不动点定理研究一类非线性分数阶积分微分方程解的存在性, 得到了其至少存在一个解和存在唯一解的结果; 其次, 通过迭代法对两个实例进行模拟仿真验证所得结果.

关键词: 分数阶积分微分方程, 模拟仿真, 存在性, 迭代法

Abstract: Firstly, by using the Banach contraction principle and Krasnoselskii fixed point theorem, we studied the existence of solutions for a class of nonlinear  fractional integro-differential equations, and obtained the result that there was at least one solution and there was a unique solution. Secondly, two examples were simulated by using the iterative method to verify the results.

Key words: fractional integro-differential equations, simulation, existence, iterative method
