Gilles Lachaud, Christophe Ritzenthaler, Alexey Zykin
Let k be a field and f be a Siegel modular form of weight h \geq 0 and genus g>1 over k. Using f, we define an invariant of the k-isomorphism class of a principally polarized abeli…

On a conjecture of Serre on abelian threefolds
Gilles Lachaud, Christophe Ritzenthaler
In this article, we give a reformulation of a result from Howe, Leprevost and Poonen on a three dimensional family of abelian threefolds. We also link their result to a conjecture…
