摘要
本文考虑了一个修正斯普罗特 C 系统。研究了该系统平衡点的稳定性和霍普夫分岔的发生。此外,通过应用正态形式理论,说明了该系统分岔周期解的稳定性、方向和周期的增加(或减少)。结果表明,在分岔值 α = 0 处的分岔周期解是不稳定的。霍普夫分岔的类型为亚临界,分岔周期解的周期会增加。
Stability and Hopf Bifurcation in a Modified Sprott C System
In this article, a Modified Sprott C system is considered. The stability of equilibrium points and the occurrence of Hopf bifurcation in the system are investigated. It has been proved that the system displays a Hopf bifurcation at α = 0. Additionally, by applying normal form theory, the stability, direction and increase (or decrease) of the period of bifurcating periodic solutions of the system are illustrated. It has been shown that the solutions of bifurcating periodic solutions at the bifurcation value α = 0 are unstable. The type of Hopf bifurcation is subcritical and the periods of the bifurcating periodic solutions increase.
