Query: Quasi-big\`ebres de Lie et cohomologie d'alg\`ebre de Lie   Lie quasi-bialgebras are natural generalisations of Lie bialgebras introduced
by Drinfeld. To any Lie quasi-bialgebra structure of finite-dimensional (G,
\mu, \gamma ,\phi ?), correspond one Lie algebra structure on D = G\oplus G*,
called the double of the given Lie quasi-bialgebra. We show that there exist on
\Lambda G, the exterior algebra of G, a D-module structure and we establish an
isomorphism of D-modules between \Lambda D and End(\Lambda G), D acting on
\Lambda D by the adjoint action.
