D.15.4.27 ChernRootsWedge

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

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)
