Deformations of minimal cohomology classes on abelian varieties
Luigi Lombardi, Sofia Tirabassi
We show that the infinitesimal deformations of the Brill--Noether locus attached to a smooth non-hyperelliptic curve are in one-to-one correspondence with the deformation…

GV-subschemes and their embeddings in principally polarized abelian varieties
Luigi Lombardi, Sofia Tirabassi
We prove that the embedding of a -subscheme in a principally polarized abelian variety does not factor through any nontrivial isogeny. As an application, we present a new proof…
