. The polynomials are expressed in the basis of monomials. muEC::SP::TableY – table of all Schubert polynomials
The muEC::SP::TableY function returns the table of all Schubert polynomials indexed by codes of permutations in . The polynomials are expressed in the basis of monomials.
When called with the second argument Pe, it returns the table of all Schubert polynomials in Sn, expressed in the dual basis of the monomial basis, i.e. the basis of products of elementary symmetric functions on an alphabet flag. For instance, Pe[1, 2, 0, 1, 0] stands for the product e1(x1,x2,x3,x4)*e2(x1,x2,x3)*e1(x1).
