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)
