摘要
本文研究了一类 2n - 1次系统 ,通过将其化为Abel方程 ,给出了极限环唯一性的充分条件 ,得到的结论推广了文献 [1 ]的主要结果 。
In this paper,a system of degree 2n-1 was studied. By transforming it into Abel equation,we obtained the sufficient conditions of the uniqueness of limit cycles. Our results have developed the main results of Literature . At the end of the paper we analyzed some specific systems.
