A Reider-type theorem for higher syzygies on abelian surfaces

Algebraic Geometry 2017-04-03 v3

Abstract

Building on the theory of infinitesimal Newton--Okounkov bodies and previous work of Lazarsfeld--Pareschi--Popa, we present a Reider-type theorem for higher syzygies of ample line bundles on abelian surfaces. As an application of our methods we confirm a conjecture of Gross and Popescu on abelian surfaces with a very ample primitive polarization of type (1,d)(1,d), whenever d23d\geq 23.
