Let be a metrizable compact abelian group, its dual group and let be a Rosenthal set. We show that whenever is a Banach space with Radon-Nikodym property and is weakly sequentially complete. We deduce a condition implying that the product of two Rosenthal sets is still a Rosenthal set in product group. Then we introduce the relative Radon-Nikodym property -, which generalizes the analytic Radon-Nikodym property. We prove that - property for implies that is finite. This gives a new and easy proof that does not possess the analytic Radon-Nikodym property.
Soient un groupe abélien compact métrisable, son groupe dual et un ensemble de Rosenthal. Nous montrons que lorsque est un espace de Banach ayant la propriété de Radon-Nikodym et est faiblement séquentiellement complet. Nous en déduisons une condition suffisante pour que le produit de deux ensembles de Rosenthal en soit encore un pour le groupe produit. Ensuite nous introduisons la propriété de Radon-Nikodym relative -, une généralisation de la propriété de Radon-Nikodym analytique. Nous montrons que si a la propriété -, alors est fini. Cela nous permet de retrouver très simplement le fait que n’a pas la propriété de Radon-Nikodym analytique
