摘要
利用Mironenko的反射数理论,研究了三元多项式微分系统的反射函数为F(t,x)=(x1,x2,F3(t,x))T,(x=x1,x2,x3)T时,F3(t,x)的具体表达式,并讨论了该系统存在周期解的条件.
Mironenko's theory of reflective function was used to study the expression of F3(t,x) when F(t,x)=(x1,x2,F3(t,x))^T,x=(x1,x2,x3)^T was the reflective function of the trinary polynominal differential system.The conditions for periodic solution which the system has were discussed too.
