用对称多项式构造求根法
On using symmetric polynomials for constructing root finding methods
摘要:
本文提出了一种构造同时求多项式根的迭代法的方法。这种方法的一个特点是利用了对称多项式的基本定理。在这个框架内,我们重建了许多现有的根查找方法。本文给出的新结果是对Durand-Kerner方法的一些改进。
英文摘要:
We propose an approach to constructing iterative methods for finding polynomial roots simultaneously. One feature of this approach is using the fundamental theorem of symmetric polynomials. Within this framework, we reconstruct many of the existing root finding methods. The new results presented in this paper are some modifications of the Durand-Kerner method.
