AI总结:

本文采用拓扑方法分析含 Caputo 导数的分数阶微分方程,提出分数阶 Conley 指数与 Lyapunov 指数计算方法,以识别混沌吸引子并揭示其分形、谱性质及稳定性。

摘要:

在本工作中,我们通过对奇异吸引子进行严格的拓扑分析,探索了分数阶微分方程(FDEs)的动力学。通过研究具有阶数为 α∈(0,1) 的 Caputo 导数的系统,我们确定了混沌行为出现的条件,其特征在于正拓扑熵以及同宿和异宿结构的存在。我们引入了计算分数阶 Conley 指数和 Lyapunov 指数的新方法,使我们能够区分混沌吸引子与非混沌吸引子。我们的结果还为分数阶系统中奇异吸引子的分形和谱性质提供了新的见解,建立了一个在此背景下理解混沌与稳定性的综合框架。

英文摘要:

In this work, we explore the dynamics of fractional differential equations (FDEs) through a rigorous topological analysis of strange attractors. By investigating systems with Caputo derivatives of order \( α\in (0, 1) \), we identify conditions under which chaotic behavior emerges, characterized by positive topological entropy and the presence of homoclinic and heteroclinic structures. We introduce novel methods for computing the fractional Conley index and Lyapunov exponents, which allow us to distinguish between chaotic and non-chaotic attractors. Our results also provide new insights into the fractal and spectral properties of strange attractors in fractional systems, establishing a comprehensive framework for understanding chaos and stability in this context.
