High-Order Melnikov Method for Time-Periodic Equations

Advanced Nonlinear Studies, 2017
This paper discusses a high-order Melnikov method for periodically perturbed equations. We introduce a new method to compute Mk⁢(t0){M_{k}(t_{0})} for all k≥0{k\geq 0}, among which M0⁢(t0){M_{0}(t_{0})} is the traditional Melnikov function, and M1⁢(t0 ...

Research on the Threshold Determination Method of the Duffing Chaotic System Based on Improved Permutation Entropy and Poincaré Mapping [PDF]

Entropy, 2023
The transition from a chaotic to a periodic state in the Duffing chaotic oscillator detection system is crucial in detecting weak signals. However, accurately determining the critical threshold for this transition remains a challenging problem ...

Chaotic motion of vibro-impact system based on Galerkin-Ivanov transformation

Xi'an Gongcheng Daxue xuebao, 2021
Based on the Galerkin-Ivanov transformation, the chaotic motion of a vibro-impact system was investigated. For a general vibro-impact system with one-side rigid, the equivalent smooth system with symmetric structure was obtained by Galerkin-Ivanov ...

Higher order stroboscopic averaged functions: a general relationship with Melnikov functions

Electronic Journal of Qualitative Theory of Differential Equations, 2021
In the research literature, one can find distinct notions for higher order averaged functions of regularly perturbed non-autonomous $T$-periodic differential equations of the kind $x'=\varepsilon F(t,x,\varepsilon)$.

Periodic solutions of a differential perturbed system via the averaging theory and the Melnikov method

Journal of Innovative Applied Mathematics and Computational Sciences, 2023
In this paper, we will study the maximum number of limit cycles of a perturbed differential system with respect to its parameters which appear in the system specially on the degree of the polynomials.
