摘要

摘要提出了一种计算在搜索多项式与整个函数的结果时产生的某些多重数列的部分和的方法。我们可以使用一种符号算法，利用牛顿递归公式求出该公式中包含的根的幂和，而无需求出系统的根。在 Maple 中实现了所提出的计算多个数值级数部分和的算法。文中给出了使用该算法求某些类多重数列的部分和的示例。

On Calculating Partial Sums of Multiple Numerical Series by Methods of Computer Algebra

Abstract

A method to calculate partial sums of some multiple numerical series arising when searching for the resultant of a polynomial and an entire function is proposed. One can apply a symbolic algorithm that uses recurrent Newton formulas to find power sums of roots included in this formula without finding the very roots of the system. The algorithm that implements the proposed approach to calculate partial sums of multiple numerical series is implemented in Maple. Examples of using this algorithm to find partial sums of some classes of multiple numerical series are given.
