| Abstract: | 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. |
