The first objective of this paper is to study the Darboux integrability of the polynomial differential system and the second one is to show that for sufficiently small this model exhibits one small amplitude periodic solution that bifurcates from the origin of coordinates when . This model was introduced by Hoover as the first example of a differential equation with a hidden attractor and it was used by Sprott to illustrate a differential equation having a chaotic behavior without equilibrium points, and now this system is known as the Sprott A system.

Sprott A系统中的可积性和零霍夫分支
本文的首要目标是研究多项式微分系统的Darboux可积性 第二个是为了证明 足够小,该模型表现出一个小幅度的周期解,该周期解从坐标原点分叉 。该模型是由Hoover引入的,它是带有隐藏吸引子的微分方程的第一个示例,并且由Sprott用来说明具有无平衡点的混沌行为的微分方程,现在该系统被称为Sprott A系统。
