Singularities of divisors of small degrees on abelian varieties

Algebraic Geometry 2023-06-01 v2

Abstract

Pareschi showed that an ample divisor of degree dd on a simple abelian variety of dimension gg has mild singularities when d<gd<g. We extend his result to general polarized abelian varieties. We also show that ample divisors of degree 33 or 44 on an abelian variety have mild singularities.
