Abstract : We provide an explicit formulation of the splitting associated with the Multiplicative Schwarz iteration. We show the advantage of considering the explicit formulation, when the iteration is used as a preconditioner of a Krylov method. // A partir d'une expression explicite du splitting défini par l'itération multiplicative de Schwarz, nous étudions son utilisation comme précondtionnement d'une méthode de Krylov.
