Twisted cubics on cubic fourfolds
Christian Lehn, Manfred Lehn, Christoph Sorger +1
We construct a new twenty-dimensional family of projective eight-dimensional irreducible holomorphic symplectic manifolds: the compactified moduli space M_3(Y) of twisted cubics on…
On the monodromy of the Hitchin connection
Yves Laszlo, Christian Pauly, Christoph Sorger
For any genus g > 1 we give an example of a family of smooth complex projective curves of genus g such that the image of the monodromy representation of the Hitchin connection on t…
Slodowy Slices and Universal Poisson Deformations
M. Lehn, Y. Namikawa, Ch. Sorger
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 centra…
A symplectic resolution for the binary tetrahedral group
Manfred Lehn, Christoph Sorger
We describe an explicit symplectic resolution for the quotient singularity arising from the four-dimensional symplectic represenation of the binary tetrahedral group.
Singular symplectic moduli spaces
Dmitry Kaledin, Manfred Lehn, Christoph Sorger
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 o…
The cup product of the Hilbert scheme for K3 surfaces
Manfred Lehn, Christoph Sorger
To any graded Frobenius algebra A we associate a sequence of graded Frobenius algebras A^[n] in such a way that for any smooth projective surface X with trivial canonical divisor t…
