With the kind permission of the author, Michael Messollen, Macaulay2 incorporates
Singular-Libfac
, version 3.1.1, a free library of routines, depending on
Singular-Factory
, that provides factorization of multivariate polynomials over finite fields and computation of the minimal associated primes of ideals via characteristic sets. It is distributed under the terms of the GNU General Public License (version 2 (see
COPYING-GPL-2
) or version 3 (see
COPYING-GPL-3
)), and is available at
ftp://www.mathematik.uni-kl.de/pub/Math/Singular/Libfac
and at
http://www.mathematik.uni-kl.de/ftp/pub/Math/Singular/SOURCES
. It is part of
Singular
, whose home page is
http://www.singular.uni-kl.de/
.
The following important routines call upon it:
factor
-- factor a ring element or a ZZ-module
gcd
-- greatest common divisor
minimalPrimes
-- minimal associated primes of an ideal
irreducibleCharacteristicSeries
-- irreducible characteristic series of an ideal
