Abstract

In this paper, we study a coupled system of beam deflection type that involves nonlinear equations with sequential Caputo fractional derivatives. Under flexible/fixed end-conditions, two main theorems on the existence and uniqueness of solutions are proved by using two fixed point theorems. Some examples are discussed to illustrate the applications of the existence and uniqueness of solution results. Another main result on the Ulam–Hyers stability of solutions for the introduced system is also discussed. Some examples of stability are discussed. New travelling wave solutions are obtained for another conformable coupled system of beam type that has a connection with the first considered system. A conclusion follows at the end.

分微分方程的梁偏转耦合系统:解的存在性、Ulam-Hyers 稳定性和行波
本文研究了一个梁挠度耦合系统,该系统涉及具有连续卡普托分数导数的非线性方程。在弹性/固定端条件下,利用两个定点定理证明了解的存在性和唯一性的两个主要定理。讨论了一些实例,以说明解的存在性和唯一性结果的应用。此外,还讨论了关于引入系统解的 Ulam-Hyers 稳定性的另一个主要结果。讨论了一些稳定性实例。对于另一个与第一个系统有关联的梁型保角耦合系统,我们得到了新的行波解。最后得出结论。

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.
