在这篇文章中,我们发展了一个严格的算法来计算系数在给定区间内的多项式的实区间零点,而不需要计算任何多项式的根。该结果将一元多项式求根的Sturm定理推广到一元区间多项式。
In this paper, we develop a rigorous algorithm for counting the real interval zeros of polynomials with perturbed coefficients that lie within a given interval, without computing the roots of any polynomials. The result generalizes Sturm’s Theorem for counting the roots of univariate polynomials to univariate interval polynomials.
