Seshadri Constants and the geometry of surfaces
Algebraic Geometry
2007-05-23 v1
Abstract
We examine how the Seshadri constant of an ample line bundle at a very general point of an algebraic surface can carry important global geometric information about the surface. In particular, we obtain a numerical criterion for when a surface admits a dominant map to an algebraic curve.
