|  |  D.15.4.33 chWedge2LP Procedure from librarychern.lib(see  chern_lib).
 
Example:Usage:
chWedge2LP(r, c ); r integer, c list of polynomials
Return:
poly
Purpose:
computes the total Chern class of the second exterior power of a vector bundle
Note:
Implementation of the formula of Lascoux, the Schur polynomials are computed
using the second Jacobi-Trudi formula (in terms of the Chern classes)
 |  | LIB "chern.lib";
ring r=0, (c(1..3)), ws(1,2,3);
list l=c(1..3);
// the total Chern class of the second exterior power of a vector bundle of rank 3
print(chWedge2LP(3, l));
==> 1+2*c(1)+c(1)^2+c(2)+c(1)*c(2)-c(3)
