D.15.35.14 topChernClass
Procedure from library schubert.lib (see schubert_lib).
- Usage:
- topChernClass(S); S sheaf
- Return:
- poly
- Input:
- S is a sheaf
- Theory:
- This is the top Chern class of a sheaf
Example:
| LIB "schubert.lib";
variety G = Grassmannian(2,4);
def R = G.baseRing;
setring R;
sheaf S = makeSheaf(G,quotientBundle);
sheaf B = S^3;
topChernClass(B);
==> 27*q(2)^2
