m_perm_2schubert_monom_summe
synopsis: INT m_perm_schubert_monom_summe(OP a,b)
description:
this routine computes the double schubert monomial
coreesponding to the
PERMUTATION object a which labeles the Schubert polynomial,
the output is the POLYNOM object b. The self part of this
POLYNOM object is to be interpreted as follows:
position 0 is the exponent of the factor (x_1 - y_1)
position 1 is the exponent of the factor (x_1 - y_2)
position 2 is the exponent of the factor (x_2 - y_1)
position 3 is the exponent of the factor (x_1 - y_3)
position 4 is the exponent of the factor (x_2 - y_2)
position 5 is the exponent of the factor (x_3 - y_1)
...
as an example look at the output of the permutation 2 3 4 1
it is the polynomial 1 [1,0,1,0,0,1] this is the product
(x_1 - y_1)(x_2 - y_1)(x_3 - y_1)
