SturmHabicht: Sturm-Habicht sequence of a polynomial

Description

Sturm-Habicht sequence of a polynomial with rational coefficients.

Usage

SturmHabicht(qspray, var = 1)

Value

A list of qspray polynomials, the Sturm-Habicht sequence of

qspray, starting with the 0-th Sturm-Habicht polynomial.

Arguments

qspray

a qspray polynomial having at most nine variables

var

index of the variable with respect to which the Sturm-Habicht sequence will be computed

Examples

library(resultant)
x <- qlone(1)
y <- qlone(2)
SturmHabicht(x^3*y^2 + 2*x*y + 1)
