SP::X2Dim
--
specialization in X Schubert basis
SP::X2Dim(schub)
schub | - | any expression in the X Schubert basis |
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.
