D.15.3.15 ChernRootsDual
Procedure from librarychern.lib (see chern_lib).
- Usage:
- ChernRootsDual(l); l a list of polynomials
- Return:
- list of polynomials
- Purpose:
- computes the Chern roots of the dual vector bundle
of a vector bundle with Chern roots from l - Note:
LIB "chern.lib"; ring r = 0, (a(1..3)), dp; // assume a(1), a(2), a(3) are the Chern roots of a vector bundle list l=a(1..3); // the Chern roots of the dual vector bundle print( ChernRootsDual(l) ); ==> [1]: ==> -a(1) ==> [2]: ==> -a(2) ==> [3]: ==> -a(3) |
