D.5.2.17 ChernRootsProd
Procedure from library chern.lib (see chern_lib).
- Usage:
- ChernRootsProd(a, b); a, b lists of polynomials
- Return:
- list of polynomials
- Purpose:
- computes the Chern roots of the tensor product of a vector bundle with Chern roots a
and a vector bundles with Chern roots b
- Note:
Example:
| | LIB "chern.lib";
ring r=0, (a(1..2), b(1..3)), dp;
list l=a(1..2);
list L=b(1..3);
// Chern roots of the tensor product of a vector bundle with Chern roots a(1), a(2)
// and a vector bundle with Chern roots b(1), b(2), b(3)
print(ChernRootsProd(l, L));
