polya_sub

synopsis: INT polya_sub(OP a,c,b)

description:

a is a POLYNOM object, b becomes the result, again a POLYNOM object, c is a INTEGER object, which gives the number of different variables in a. There is the substitution x_i becomes 1 + q^i, so the result is a POLYNOM object in one variable.

example:

 Computes the Polya substitution in a Schur polynomial.

#include "def.h"
#include "macro.h"

 main()
 {
 OP a,b,c,d;
 anfang();

 a=callocobject(); b=callocobject();
 c=callocobject(); d=callocobject();

 scan(PARTITION,a);println(a);
 scan(INTEGER,b);println(b);
 compute_schur_with_alphabet(a,b,c);println(c);
 polya_sub(c,b,d); println(d);

 freeall(a); freeall(b); freeall(c); freeall(d);
 ende();
 }
