RealRoots :: SylvesterSequence

SylvesterSequence -- the Sylvester sequence of two rational univariate polynomials

Synopsis

Description

This computes the Sylvester sequence of two rational univariate polynomials f and g in the same ring.

i1 : R = QQ[t]

o1 = R

o1 : PolynomialRing
i2 : f = (t + 1)*(t + 2)

      2
o2 = t  + 3t + 2

o2 : R
i3 : g = t + 2

o3 = t + 2

o3 : R
i4 : SylvesterSequence(f,g)

o4 = {t + 1, 1, 0}

o4 : List
