Singular Manual: ChernRootsProd

| #### D.5.2.17 ChernRootsProd Procedure from library `chern.lib` (see chern_lib). Usage: ChernRootsProd(a, b); a, b lists of polynomials Return: list of polynomials Purpose: computes the Chern roots of the tensor product of a vector bundle with Chern roots a and a vector bundles with Chern roots b Note: Example:
    LIB "chern.lib";
    ring r=0, (a(1..2), b(1..3)), dp;
    list l=a(1..2);
    list L=b(1..3);
    // Chern roots of the tensor product of a vector bundle with Chern roots a(1), a(2)
    // and a vector bundle with Chern roots b(1), b(2), b(3)
    print(ChernRootsProd(l, L));
