[Une algèbre de Hopf associée à une paire de Lie]
Le quotient d'une paire d'algébroïdes de Lie est un objet algèbre de Lie dans la catégorie dérivée de la catégorie des modules à gauche sur . Dans cette note, nous décrivons l'algèbre enveloppante universelle de l'objet algèbre de Lie et nous prouvons que celle-ci constitue un objet algèbre de Hopf dans .
The quotient of a pair of Lie algebroids is a Lie algebra object in the derived category of the category of left -modules, the Atiyah class being its Lie bracket. In this note, we describe the universal enveloping algebra of the Lie algebra object and we prove that it is a Hopf algebra object in .
