一些非光滑Lienard系统的小扰动极限环(英文)

Small-amplitude limit cycles of some non-smooth Lienard systems

根据韩茂安等所得到的计算非光滑Lienard系统的焦点量的方法,应用maple程序,给出一些较一般的非光滑Lienard系统从原点处分支出的极限环数目.

Based on the results by HAN Mao-an, et al. for computing some focus values of non-smooth Lienard systems, the number of limit cycles bifurcated from the origin of some more general non-smooth Li^nard systems were given by using maple process.
