D.2.8.2 elemSymmId

Procedure from library poly.lib (see poly_lib).

Return:
ideal of elementary symmetric polynomials for 1-st n
variables of basering

Example:
 
LIB "poly.lib";
ring R = 0, (v,w,x,y,z), lp;
elemSymmId(3);
==> _[1]=v+w+x
==> _[2]=vw+vx+wx
==> _[3]=vwx
elemSymmId(nvars(basering));
==> _[1]=v+w+x+y+z
==> _[2]=vw+vx+vy+vz+wx+wy+wz+xy+xz+yz
==> _[3]=vwx+vwy+vwz+vxy+vxz+vyz+wxy+wxz+wyz+xyz
==> _[4]=vwxy+vwxz+vwyz+vxyz+wxyz
==> _[5]=vwxyz
