Multivariate Polynomials and Polynomial Rings
=============================================

Sage implements multivariate polynomial rings through several
backends. The most generic implementation uses the classes
:class:`sage.rings.polynomial.polydict.PolyDict` and
:class:`sage.rings.polynomial.polydict.ETuple` to construct a dictionary with
exponent tuples as keys and coefficients as values.

Additionally, specialized and optimized implementations over many
specific coefficient rings are implemented via a shared library interface to
SINGULAR; and polynomials in the boolean polynomial ring

.. math::

    \GF{2}[x_1,...,x_n]/ \langle x_1^2+x_1,...,x_n^2+x_n \rangle.

are implemented using the PolyBoRi library (cf. :mod:`sage.rings.polynomial.pbori`).
