摘要
通过把高次奇点转化为初等奇点的方法,对一类四次系统高次奇点的奇点量与可积性进行了研究。通过计算该系统奇点量的代数递推公式,得到该系统在原点的前30个奇点量,推导出系统在原点邻域可积的必要条件,并证明了其充分性。
Generalized singular point quantity and integrability of the degenerate resonant singular point for a quartic polynomial system were studied.Firstly,algebraic recursive formulas for computing singular point quantities of the origin are derived.The first 30th singular point values are given by using compute algebra mathematica.Then the necessary conditions for the integrability were worked out.At last,the sufficiencies of these conditions were proved.
