SAERationalFunctionAlgFactor(UP, SAE, UPA) : SIG == CODE where
UP : UnivariatePolynomialCategory Fraction Polynomial Integer
SAE : Join(Field, CharacteristicZero,
MonogenicAlgebra(Fraction Polynomial Integer, UP))
UPA: UnivariatePolynomialCategory SAE
SIG ==> with
factor : UPA -> Factored UPA
++ factor(p) returns a prime factorisation of p.
CODE ==> add
factor q ==
factor(q, factor$RationalFunctionFactor(UP)
