摘要

本文研究了一个非线性分数微分方程的初值问题,该方程具有相对于另一个函数的可变阶的卡普托分数导数。由于所考虑的可变阶分数导数不具有半群性质,因此在研究相应微分方程的存在性时遇到了困难。在本文中,我们引入了所考虑的变阶分数导数的近似分片常数近似和给定初值问题的近似解。然后,我们研究了变阶 Ψ 调和 Caputo 分微分方程近似解的存在性和 Ulam 型稳定性。作为我们结果的一个部分案例,我们得到了具有片常数阶Ψ阶卡普托分数导数的微分方程的乌拉姆型稳定性结果。

Ulam-Type Stability Results for Variable Order Ψ-Tempered Caputo Fractional Differential Equations
An initial value problem for nonlinear fractional differential equations with a tempered Caputo fractional derivative of variable order with respect to another function is studied. The absence of semigroup properties of the considered variable order fractional derivative leads to difficulties in the study of the existence of corresponding differential equations. In this paper, we introduce approximate piecewise constant approximation of the variable order of the considered fractional derivative and approximate solutions of the given initial value problem. Then, we investigate the existence and the Ulam-type stability of the approximate solution of the variable order Ψ-tempered Caputo fractional differential equation. As a partial case of our results, we obtain results for Ulam-type stability for differential equations with a piecewise constant order of the Ψ-tempered Caputo fractional derivative.
