摘要
讨论Abel方程闭解的存在性、个数和稳定性,改进了以前文献的结果,并利用关于Abel方程的这些结果得到了一类n次多项式系统在一定条件下极限环的个数和稳定性.
In this paper, the existence, number and stability of Abel equation's closed solutions are discussed, and the results in previous papers are improved. Moreover, the number and stability of the limit cycles of a class of polynomial system with degree n are studied under some conditions by means of the results about Abel equation.
