Abstract:

We show that polarisations of type $(1,...,1,2g+2)$ on $g$-dimensional abelian varieties are never very ample, if $g\geq 3$. This disproves a conjecture of Debarre, Hulek and Spandaw. We also give a criterion for non-embeddings of abelian varieties into $2g+1$-dimensional linear systems.
