A new family of rational surfaces in P^4
Hans-Christian Graf v. Bothmer, Cord Erdenberger, Katharina Ludwig
We describe a new method of constructing rational surfaces with given invariants in P^4 and present a family of degree 11 rational surfaces of sectional genus 11 with 2 six-secants…
Last syzygies of 1-generic spaces
Hans-Christian v. Bothmer
Consider a determinantal variety X of expected codimension definend by the maximal minors of a matrix M of linear forms. Eisenbud and Popescu have conjectured that 1-generic matric…
Geometric syzygies of elliptic normal curves and their secant varieties
Hans-Christian v. Bothmer, Klaus Hulek
We show that the linear syzygy spaces of elliptic normal curves, their secant varieties and of bielliptic canonical curves are spanned by geometric syzygies.
Geometric Syzygies of Canonical Curves of even Genus lying on a K3-Surface
Hans-Christian v. Bothmer
Based on a recent result of Voisin [2001] we describe the last nonzero syzygy space in the linear strand of a canonical curve C of even genus g=2k lying on a K3 surface, as the amb…
