任何多项式方程的根

The roots of any polynomial equation

Geert-Jan Uytdewilligen

摘要:

给出了一般多项式方程a[n]*x^n+a[n-1]*x^(n-1)+.+ a1*x+a0=0。为此,我们将x表示为s的幂级数,并计算前n-2个系数。我们将多项式方程转化为以根为解的微分方程。然后将幂级数的系数表示在前n-2个系数中。然后变量s被设置为a0。增加一个自由参数使级数收敛。

英文摘要:

We provide a method for solving the roots of the general polynomial equation a[n]*x^n+a[n-1]*x^(n-1)+..+a1*x+a0=0. To do so, we express x as a powerseries of s, and calculate the first n-2 coefficients. We turn the polynomial equation into a differential equation that has the roots as solutions. Then we express the powerseries' coefficients in the first n-2 coefficients. Then the variable s is set to a0. A free parameter is added to make the series convergent.
