On the Cobordism Class of the Hilbert Scheme of a Surface

- G. Ellingsrud, L. Gottsche, M. Lehn
- Mathematics
- 19 April 1999

Let S be a smooth projective surface and S [n] the Hilbert scheme of zerodimensional subschemes of S of length n. We proof that the class of S [n] in the complex cobordism ring depends only on the… Expand

Chern classes of tautological sheaves on Hilbert schemes of points on surfaces

- M. Lehn
- Mathematics
- 20 March 1998

Abstract. We give an algorithmic description of the action of the Chern classes of tautological bundles on the cohomology of Hilbert schemes of points on a smooth surface within the framework of… Expand

The cup product of Hilbert schemes for K3 surfaces

- M. Lehn, Christoph Sorger
- Mathematics
- 1 May 2003

Abstract.To any graded Frobenius algebra A we associate a sequence of graded Frobenius algebras A[n] so that there is canonical isomorphism of rings (H*(X;ℚ)[2])[n]≅H*(X[n];ℚ)[2n] for the Hilbert… Expand

Singular symplectic moduli spaces

- D. Kaledin, M. Lehn, Christoph Sorger
- Mathematics
- 10 April 2005

Moduli spaces of semistable sheaves on a K3 or abelian surface with respect to a general ample divisor are shown to be locally factorial, with the exception of symmetric products of a K3 or abelian… Expand

Stable pairs on curves and surfaces

- D. Huybrechts, M. Lehn
- Mathematics
- 9 November 1992

We describe stability conditions for pairs consisting of a coherent sheaf and a homomorphism to a fixed coherent sheaf on a projective variety. The corresponding moduli spaces are constructed for… Expand

Irreducibility of the punctual quotient scheme of a surface

- Mathematics
- 15 April 1997

AbstractIt is shown that the punctual quotient schemeQlr parametrizing all zero-dimensional quotients

On the symplectic eightfold associated to a Pfaffian cubic fourfold

- N. Addington, M. Lehn
- Mathematics
- 22 April 2014

We show that the irreducible holomorphic symplectic eightfold Z associated to a cubic fourfold Y not containing a plane is deformation-equivalent to the Hilbert scheme of four points on a K3 surface.… Expand

Slodowy slices and universal Poisson deformations

- M. Lehn, Y. Namikawa, Christoph Sorger
- Mathematics
- Compositio Mathematica
- 22 February 2010

Abstract We classify the nilpotent orbits in a simple Lie algebra for which the restriction of the adjoint quotient map to a Slodowy slice is the universal Poisson deformation of its central fibre.… Expand
