    initial v1  
    1 See: http://wiki.sagemath.org/combinat/MultivariatePolynomials
     1We build an implantation of polynomials as formal sum of exponents. This allows to work on any number of variables with some easy morphism. We use some actions of Weyl group on the exponents to create operators (especially divided difference operators).

     3These operators allow us to build different bases that comes from geometry and have nice combinatorial description.
