Dans cet article, nous étudions le comportement des groupes d’inertie pour des représentations galoisiennes modulaires mod et dans quelques cas on démontre une généralisation du resultat de descente de niveau de Ribet (cf. [9]).
In this article we study the behavior of inertia groups for modular Galois mod representations and in some cases we give a generalization of Ribet’s lowering the level result (cf. [9]).
