D.5.2.5 chern
Procedure from library chern.lib (see chern_lib).
- Usage:
- chern(s); s list of polynomials
- Return:
- list of polynomials
- Purpose:
- computes the list of the Chern classes up to degree N
in terms of the Segre classes from s
- Note:
Example:
| LIB "chern.lib";
ring r = 0, (s(1..3)), dp;
list l=s(1..3);
// Chern classes in Segre classes s(1), s(2), s(3)
print( chern(l) );
// This procedure is inverse to segre(...). Indeed:
print( segre(chern(l), 3) );
