computes the Chern classes 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)), dp;
list l=c(1..2);
// the Chern classes of the second symmetric power of a vector bundle of rank 2
print( chSymm2L(2, l));
==> [1]:
==> 3
==> [2]:
==> [1]:
==> 3*c(1)
==> [2]:
==> 2*c(1)^2+4*c(2)
==> [3]:
==> 4*c(1)*c(2)
