The first 3 focus quantities and the first 3 saddle quantities are derived simply and quickly with the formulas for real planar quadratic systems
利用這一公式我們極其簡捷地推導出二次系統的前三個焦點量和鞍點量公式。In chapter 2, by studying the computation of the quantities of singular point of the original of the following complex autonomous polynomial differential system two linear recursion formulas for the computation of quantities of singular point of system ( 1 ) are obtained. applicable formulas are presented unitedly for the computation of focus quantities and saddle quantities, which play an important role in center - focus determination and bifurcation of limit cycles in real planar polynomial differential systems
在第二章,我們研究平面多項式復自治微分系統原點的奇點量計算,得到了奇點量計算的線性代數遞推公式,統一地給出了在實平面多項式微分系統的中心焦點判定與極限環分支中有著極為重要意義的焦點量與鞍點量的易於應用的計算公式。
