Approximate Chaotic Solutions of the Lu System

摘要

This paper applies the multistage homotopy-perturbation method (MHPM) to the Lu system, which bridges the gap between the Lorenz system and the Chen system. Approximate closed-form expressions of the chaotic attractor are derived. Numerical comparison between the MPHM and the fourth-order Runge-Kutta method is carried out, revealing that the method is a powerful tool for analyzing and understanding chaos.
