This package implements different bases of the algebra of multivariate polynomials using SageMath. This work has been started in 2010 and was distriuted in the Sage-combinat experimental package which does not exist anymore. That is why we know offer it as an extra Sage package.

sage 9.

$ sage -pip install multipolynomial_bases

Download the source from the github and run this command from the repo root:

$ sage  -pip install --upgrade --no-index -v .

Equivalently, you can use the Makefile install command:

$ make install

Once installed, you can use it in sage by importing the features:

sage: from multipolynomial_bases import *
sage: A.<x> = MultivariatePolynomialAlgebra(QQ)
sage: A
The Multivariate polynomial algebra on x over Rational Field

The (partially written) documentation is available here.
