Seshadri Constants and the geometry of surfaces

Michael Nakamaye

Published 2003-01-22Version 1

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.
