Donaldson–Thomas invariants, linear systems and punctual Hilbert schemes

چکیده
We study certain DT invariants arising from stable coherent sheaves in a nonsingular projective threefold supported on the members of linear system fixed line bundle. When canonical bundle satisfies positivity conditions, we relate to Carlsson-Okounkov formulas for twisted Euler's number punctual Hilbert schemes surfaces, and conclude they have modular property.

Intersection theory on punctual Hilbert schemes and graded Hilbert schemes
The rational Chow ring A(S,Q) of the Hilbert scheme S parametrising the length n zero-dimensional subschemes of a toric surface S can be described with the help of equivariant techniques. In this paper, we explain the general method and we illustrate it through many examples. In the last section, we present results on the intersection theory of graded Hilbert schemes.
متن کاملThe Chow ring of punctual Hilbert schemes on toric surfaces
Let X be a smooth projective toric surface, and H(X) the Hilbert scheme parametrising the length d zero-dimensional subschemes of X . We compute the rational Chow ring A(H(X))Q. More precisely, if T ⊂ X is the twodimensional torus contained in X , we compute the rational equivariant Chow ring AT (H (X))Q and the usual Chow ring is an explicit quotient of the equivariant Chow ring. The case of s...
متن کاملIrreducible components of the equivariant punctual Hilbert schemes
Let Hab be the equivariant Hilbert scheme parametrizing the 0-dimensional subschemes of the affine plane invariant under the natural action of the one-dimensional torus Tab := {(t, t) t ∈ k}. We compute the irreducible components of Hab: they are in one-one correspondence with a set of Hilbert functions. As a by-product of the proof, we give new proofs of results by Ellingsrud and Strømme, name...
متن کاملGröbner Strata in the Punctual Hilbert Scheme
Given a standard set δ of a finite size r, we show that the functor associating to a k-algebra B the set of all reduced Gröbner bases with standard set δ is representable. We show that the representing scheme Hilb′ δ k[x]/k is a locally closed stratum in the punctual Hilbert scheme Hilbrk[x]/k. Moreover, we cover the punctual Hilbert scheme by open affine subschemes attached to all standard set...
متن کاملTopological Properties of Punctual Hilbert Schemes of Symplectic 4-dimensional Manifolds
In this article, we study topological properties of Voisin’s almost-complex and symplectic punctual Hilbert schemes of a 4-manifold. We describe the ring structure and the cobordism class of these Hilbert schemes and we prove in this context a particular case of Ruan’s crepant conjecture.
