D.15.2.16 chDual
Procedure from library chern.lib (see chern_lib).
- Usage:
- chDual(c); c list of polynomials
- Return:
- list of polynomials
- Purpose:
- computes the list of Chern classes of the dual vector bundle
- Note:
Example:
| LIB "chern.lib";
// Chern classes of a vector bundle that is dual to a vector bundle
// with Chern classes c(1), c(2), c(3)
ring r=0, (c(1..3)), dp;
list l=c(1..3);
print(chDual(l));
==> [1]:
==> -c(1)
==> [2]:
==> c(2)
==> [3]:
==> -c(3)
