Nous étudions des propriétés générales de continuité pour une famille croissante d’espaces de Banach de symboles pseudo-différentiels, où a été introduit par J. Sjöstrand en 1993. Nous montrons que les opérateurs associés à ces symboles sont des opérateurs de Schatten-von Neumann d’ordre sur . Nous prouvons aussi que et que si . Si par contre , alors . En modifiant la définition des espaces , on obtient aussi des classes de symboles apparentés aux espaces .
We study general continuity properties for an increasing family of Banach spaces of classes for pseudo-differential symbols, where was introduced by J. Sjöstrand in 1993. We prove that the operators in are Schatten-von Neumann operators of order on . We prove also that and , provided . If instead , then . By modifying the definition of the -spaces, one also obtains symbol classes related to the spaces.
