factory Subpackage of Singular

Factory is a C++ class library that implements a recursive representation of multivariate polynomial data. It handles sparse multivariate polynomials over different coefficient domains, such as Z, Q and GF(q), as well as algebraic extensions over Q and GF(q) in an efficient way. Factory includes algorithms for computing univariate and multivariate gcds, resultants, chinese remainders, and algorithms to factorize multivariate polynomials and to compute the absolute factorization of multivariate polynomials with integer coefficients.
