• Resumen

  • 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.
