Sur un résultat d'Imin Chen. (Avec Bart de Smit)

Prépublication de l'I.R.M.A.R. 99-53

Summary

We generalize a result of Chen concerning an isogeny between products of jacobians of modular curves associated to subgroups of~$\GL_2(\FF_p)$. This generalization concerns objects with an action by $\GL_2(\FF)$, with $\FF$ an arbitrary finite field, in more general additive categories.
