AI总结:

本文发展了Euler-Lagrange方法,通过计算由函数$P'(z)/P(z)$的Taylor和Laurent级数系数构建的Hadamard行列式之比的极限,求解任意复多项式的所有根。

摘要:

本文发展了Euler-Lagrange方法,并基于Hadamard行列式之比极限的计算(类似于Bernoulli-Aitken-Nikiporets方法),计算任意复多项式$P(z)$的所有根,其中Hadamard行列式由函数$\ rac{P'(z)}{P(z)}$的Taylor和Laurent级数展开的系数构建。

英文摘要:

In the article we develop Euler-Lagrange method and calculate all the roots of an arbitrary complex polynomial $P(z)$ on the base of calculation (similar to the Bernoulli-Aitken-Nikiporets methods) of the limits of ratios of Hadamard determinants built by means of coefficients of expansions into Taylor and Laurent series of the function~$\frac{P'(z)}{P(z)}$.
