摘要
研究一类平面分段光滑二次系统,基于Melnikov函数和一类多项式函数孤立零点的个数,证明了该二次系统存在16个极限环.
A class of planar piecewise smooth quadratic differential system is studied. It is proved that the system exists16 limit cycles based on Melnikov function and isolated zero of a class of polynomial function.piecewise smooth quadratic differential
