D.5.2.33 chWedge2LP

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));
