摘要

这项工作的目的是提出一个带初值问题的高分数阶微分方程系统的数值解。为了实现这一目标，我们提出了一个新颖的理论结果，旨在将这些高分数阶系统简化为 $\alpha $-分数系统，其中 $0<\alpha \le 1$，然后应用一种称为修正分数欧拉法的最新数值方法，该方法被视为分数欧拉法（FEM）的数值修正。最后，我们将利用 MATLAB 程序给出数值应用来说明我们的结果。

A robust scheme for reduction of higher fractional-order systems

The objective of this work is to present a numerical solution to a system of higher fractional-order differential equations with initial value problems. In order to achieve this objective, we develop a novel theoretical result aimed to reduce these higher fractional-order systems to $\alpha $-fractional systems, where $0<\alpha \le 1$, and then apply a recent numerical approach called modified fractional Euler method, which is regarded a numerical modification of the fractional Euler Method (FEM). Finally, we will give numerical applications to illustrate our results using MATLAB procedures.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
