The abelian fibration on the Hilbert cube of a K3 surface of genus 9
Atanas Iliev, Kristian Ranestad
In this paper we construct an abelian fibration over on the Hilbert cube of the primitive K3 surface of genus 9. After the abelian fibration constructed by Mukai on the…
An elementary, explicit, proof of the existence of Hilbert schemes of points
Trond Gustavsen, Dan Laksov, Roy Skjelnes
We give a short, elementary and explicit proof of the existence of Hilbert schemes of points on affine schemes. As a direct consequence we obtain the existence of the Hilbert schem…
Schubert Unions in Grassmann Varieties
Johan P. Hansen, Trygve Johnsen, Kristian Ranestad
We study subsets of Grassmann varieties G(l,m) over a field F, such that these subsets are unions of Schubert cycles, with respect to a fixed flag. We study the linear spans of, an…
On the cotangent cohomology of rational surface singularities with almost reduced fundamental cycle
Trond Stolen Gustavsen
We prove dimension formulas for the cotangent spaces and for a class of rational surface singularities by calculating a correction term in the general dimension for…
