*Utilities for polynomials with rational coefficients.*

This package deals with polynomials, univariate and multivariate,
with rational coefficients. Features include:

resultant of two multivariate polynomials

subresultants of two multivariate polynomials

greatest common divisor of two multivariate polynomials

integral division (aka division without remainder) of two
multivariate polynomials

Sturm-Habicht sequence of a multivariate polynomial

square-free factorization of a multivariate polynomial

number of real roots of a univariate polynomial in a given
interval

division with remainder of two univariate polynomials

See this
blog post for an illustration of the resultant.
