Singular Manual: chSymm2LP

| #### D.5.2.30 chSymm2LP Procedure from library `chern.lib` (see chern_lib). Usage: chSymm2LP(r, c); r integer, c list of polynomials Return: poly Purpose: computes the total Chern class of the second symmetric power of a vector bundle Note: Implementation of the formula of Lascoux, the Schur polynomials are computed using the second Jacobi-Trudi formula (in terms of the Chern classes) Example:
    LIB "chern.lib";
    ring r=0, (c(1..2)), ws(1, 2);
    list l=c(1..2);
    // the total Chern class of the second symmetric power of a vector bundle of rank 2
    print( chSymm2LP(2, l));
