Projective normality of abelian surfaces of type (1,2d)

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/67675We show that an abelian surface embedded in P^N by a very ample line bundle L of type (1,2d) is projectively normal if and only if d>=4. This completes the study of the projective normality of abelian surfaces embedded by complete linear systems.14 pagesAlgebraic Geometry14K05; 14N05, 14E20Projective normality of abelian surfaces of type (1,2d)text
