焦点量的一种计算方法

A Method of Calculating the Focal Quantities

通过代换将一般n次多项式微分系统的焦点量的计算问题转化为等价的二次Abel系统的焦点量的计算,并利用后继函数法得到了焦点量计算的线性递推公式.

We transforme the calculation problem for the focal quantities of a class n order polynomial differential system into the same problem of the 2 order equivalent Abel system based on the variable substitution, and a linear recursive formula for computing focal quantities of a class n order polynomial differential system is given by the return map method.
