一类平面多项式微分系统极限环的存在唯一性

The Existence And Uniqueness of Limit cycles in A class of Planar Polynomail Differential System

本文研究一类平面多项式微分系统的极限环,得到了系统极限环存在、唯一的充分条件.

In this paper. We are concerned with the limit cycles of a class of planar polynomial differential system. Suffecient conditions for the existence and uniqueness of limit cycle in this system are obtained.
