THE UNIQUENESS OF LIMIT CYCLE AND CRITICAL POINT FOR A CLASS OF CUBIC system
收藏 引用
Annals of Differential Equations 2008年 第2期24卷 157-162页
作者: Jin Shan,Lu Shiping(College of Math. and Computer Science,Anhui Normal University,Wuhu 241000,Anhui)
In this paper,we consider an accompany system concerning some class of cubic system. We then prove that the system has at most one limit cycle. Finally,we obtain the topological structure of both the critical points a... 详细信息

THE UNIQUENESS OF LIMIT CYCLE AND THE STRUCTURE OF CRITICAL POINT AT INFINITY FOR A CLASS OF CUBIC system
收藏 引用
Annals of Differential Equations 2005年 第3期21卷 474-479页
作者: Xie Xiangdong Chen Fengde Dept. of Math. Ningde Teachers College Ningde 352100 College of Math. and Computer Science Fuzhou University Fuzhou 350002
A class of cubic system, which is an accompany system of a quadratic differential one, is studied. It is proved that the system has at most one limit cycle, and the critical point at infinity is a higher order one. Th... 详细信息
