Singular Manual: chHE

| #### D.15.4.12 chHE Procedure from library `chern.lib` (see chern_lib). Usage: chHE(c); c list of polynomials Return: polynomial Purpose: computes the highest relevant term of the Chern character Note: uses the elimination and is extremely inefficient, is included just for comparison with chAll(c) Example:
    LIB "chern.lib";
    ring r = 0, (c(1..3)), dp;
    list l=c(1..3);
    //the third degree term of the Chern character
    print( chHE(l) );
    ==> 1/6*c(1)^3-1/2*c(1)*c(2)+1/2*c(3)
