# PolynomialGcdPackage(E, OV, R, P)¶

This package computes multivariate polynomial gcd's using a hensel lifting strategy. The contraint on the coefficient domain is imposed by the lifting strategy. It is assumed that the coefficient domain has the property that almost all specializations preserve the degree of the gcd.

gcd: (P, P) -> P
gcd(p, q) computes the gcd of the two polynomials p and q.
gcd: (SparseUnivariatePolynomial P, SparseUnivariatePolynomial P) -> SparseUnivariatePolynomial P
gcd(p, q) computes the gcd of the two polynomials p and q.
gcd: List P -> P
gcd(lp) computes the gcd of the list of polynomials lp.
gcd: List SparseUnivariatePolynomial P -> SparseUnivariatePolynomial P
gcd(lp) computes the gcd of the list of polynomials lp.
gcdPrimitive: (P, P) -> P
gcdPrimitive(p, q) computes the gcd of the primitive polynomials p and q.
gcdPrimitive: (SparseUnivariatePolynomial P, SparseUnivariatePolynomial P) -> SparseUnivariatePolynomial P
gcdPrimitive(p, q) computes the gcd of the primitive polynomials p and q.
gcdPrimitive: List P -> P
gcdPrimitive lp computes the gcd of the list of primitive polynomials lp.
