Résume
A classical theorem of Abrashkin/Fontaine states that there is no abelianvariety over Q with good reduction everywhere. We will explain the proofof the following extension : For p at most 19, the only semi-stableabelian varietiesover Q with good reduction everywhere except at p, are isogenous to apower of J_0(p)
