TLDR
In this paper, the problem of enumerative geometry of the vector bundle of rank d over H d has been studied in the context of the description of the smooth structure of the 4-manifold underlying a smooth algebraic surface.Abstract:
Let S be a smooth irreducible algebraic surface over ℂ, H d a Hilbert scheme of 0-dimensional subschemes of length d in S, dim H d = 2d, and Z d ⊂ S × H d a universal family with natural projections \(S\xleftarrow{{{\tau _d}}}{Z_d}\xrightarrow{{{\pi _d}}}{H_d}\). Fix an arbitrary divisor D on S and denote \(\varepsilon _D^d = {\pi _{d*}}\tau _d^*{O_S}(D)\). Since π d is a flat finite morphism of degree d, the sheaf e D d is in fact the vector bundle of rank d over H d . We call e D d the standard vector bundle over H d . The problem of computation of its Segre classes is connected with a number of questions of enumerative geometry. In recent times it has got applications to the description of the smooth structure of the 4-manifold underlying S — see [10].read more

Segre classes and Hilbert schemes of points
TL;DR: In this article, the integrals of the top Segre classes of tautological bundles over the Hilbert schemes of points of a K3 surface X were derived via equivariant localization of the virtual fundamental classes of Quot schemes on X. The resulting recursions are then solved explicitly.

Higher rank Segre integrals over the Hilbert scheme of points
TL;DR: In this article, the Segre classes of tautological bundles for all ranks s over all K-trivial surfaces were derived, and conjectural formulas for certain series of Verlinde Euler characteristics over the Hilbert schemes of points were given.

Tautological integrals on symmetric products of curves
TL;DR: In this paper, a conjecture on the generating series of Chern numbers of tautological bundles on symmetric products of curves was proposed, and the rank 1 and rank −1 case of this conjecture was established.
