Unirational Surfaces on the Noether Line

Algebraic Geometry 2008-12-08 v3 Number Theory

Abstract

We show that among simply connected surfaces of general type unirationality is a common feature, even when fixing the positive characteristic or numerical invariants. To do so, we construct unirational Horikawa surfaces in abundance.
