Query: Generators for the cohomology ring of Hilbert schemes of points on
  surfaces   Using the methods developed in [LQW], math.AG/0009132, we obtain a second set
of generators for the cohomology ring of the Hilbert scheme of points on an
arbitrary smooth projective surface over the field of complex numbers. These
generators have clear and simple geometric as well as algebraic descriptions.
