Projective normality of abelian surfaces of type (1,2d)
Luis Fuentes Garcia
We 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…

A note on Abelian varieties embedded in quadrics
Luis Fuentes Garcia
We show that if A is a d-dimensional abelian variety in a smooth quadric of dimension 2d then d=1 and A is an elliptic curve of bidegree (2,2) on a quadric. This extends a result o…
