D.15.2.27 ChernRootsWedge
Procedure from library chern.lib (see chern_lib).
- Usage:
- ChernRootsWedge(m, l); m integer, l a list of polynomials
- Return:
- list of polynomials
- Purpose:
- computes the Chern roots of m-th exterior power
of a vector bundle with Chern roots from l
- Note:
- makes sense only for list of polynomials
Example:
| LIB "chern.lib";
ring r=0, (a(1..3)), dp;
list l=a(1..3);
// the Chern roots of the second exterior power of a vector bundle
// with Chern roots a(1), a(2), a(3)
print( ChernRootsWedge(2, l) );
==> [1]:
==> a(2)+a(3)
==> [2]:
==> a(1)+a(3)
==> [3]:
==> a(1)+a(2)
