SP::X2Dim --
specialization in X Schubert basis
Call(s)
SP::X2Dim(schub)
Parametersschub | - | any expression in the X Schubert basis |
Introduction
The SP::X2Dim function specializes in x.i=1 all Schubert polynomials
in schub, expressed in X Schubert basis.
When used with the second argument q, it specializes in
x.i=q^(i-1) all Schubert
polynomials.
Example 1>> muEC::SP::X2Dim(a*X[3,1,2] - b*X[2,3,1,5,4] + c^3);

a - 4 b + c
>> muEC::SP::X2Dim(X[2,3,1,5,4] - a*X[3,1,4,2], q);
