| #### D.5.2.27 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)
