常系数非齐次线性差分方程(组)求特解的新方法

A new method of finding a particular solution to nonhomogeneous linear difference equations with constant coeffients

定义一种作用在形式幂级数上的算子,并结合升幂综合除法,将它应用于一类常系数非齐次线性差分方程(组)的求特解问题中.

An operator is defined to act on formal power series and,by using synthetic division of ascending power,can apply to nonhomogeneous linear difference equations with constant coefficients to find a particular solution.
