Sur un r'esultat d'Imin Chen, by Bart de Smit and Bas Edixhoven

We generalize a result of Chen concerning an isogeny between products of jacobians of modular curves associated to subgroups of GL(2,Fp). This generalization concerns objects with an action by GL(2,F) with F an arbitrary finite field, in more general additive categories.
