We study open subgroups G of SL 2 (ℤ ℓ ) n in terms of some associated Lie algebras without assuming that G is a pro-ℓ group, thereby extending a theorem of Pink. The result has applications to the study of families of Galois representations.

Nous étudions les sous-groupes ouverts G de SL 2 (ℤ ℓ ) n en termes de certaines algèbres de Lie, et ceci sans supposer que G est un groupe pro-ℓ. Le résultat étend un théorème dû à Pink et a des applications à l’étude de certaines familles de représentations galoisiennes.
