R. Fefferman a montré que sur un espace-produit à deux facteurs un opérateur borné sur est également borné de dans BMO du produit si l’oscillation moyenne sur un rectangle de l’image d’une fonction bornée supportée en dehors d’un multiple de est dominée par pour un . Nous montrons ici que ce résultat n’est plus vrai en général pour un produit de trois facteurs ou plus mais s’étend à ce cas lorsque l’opérateur est un opérateur de convolution et . Également nous montrons que les bicommutateurs de Calderón-Coifman, obtenus à partir des commutateurs de Calderón par produit tensoriel multilinéaire, sont bornés sur avec une croissance de norme polynomiale.
R. Fefferman has shown that, on a product-space with two factors, an operator T bounded on maps into BMO of the product if the mean oscillation on a rectangle R of the image of a bounded function supported out of a multiple R’ of R, is dominated by , for some . We show that this result does not extend in general to the case where E has three or more factors but remains true in this case if in addition T is a convolution operator, provided . We also show that the Calderon-Coifman bicommutators, obtained from the Calderon commutators by multilinear tensor product, are bounded on with norms growing polynomially.
