Nous donnons des conditions suffisantes pour qu'un sous-groupe donné du groupe des difféomorphismes d'une variété indéfiniment differentiable ou réelle analytique ait une structure compatible de groupe de Lie. En utilisant ces résultats, ainsi que des travaux récents concernant la paramétrisation des automorphismes CR par leur jets en un point et leur systèmes complets, nous donnons des conditions sous lesquelles le groupe des automorphismes CR globaux d'une variété CR est un groupe de Lie relativement à une topologie appropriée.
We give general sufficient conditions to guarantee that a given subgroup of the group of diffeomorphisms of a smooth or real-analytic manifold has a compatible Lie group structure. These results, together with recent work concerning jet parametrization and complete systems for CR automorphisms, are then applied to determine when the global CR automorphism group of a CR manifold is a Lie group in an appropriate topology.
