Résumé
Abstract

Nous examinons les conditions nécessaires et suffisantes pour quʼune fonctionelle bilinéaire continue sur $L^{p} (R^{d}) \otimes E$ , $p > 1$ , E étant un espace de Banach séparable, peut être étendue à une fonctionnelle linaire sur $L^{p} (R^{d}; E)$ . Lʼextension permet une généralisation de lʼH-distribution, qui fournit lʼamélioration dʼun résultat de moyennisation en vitesse (hétèrogène) sur le cadre $L^{p}$ pour tout $p > 1$ .

We examine necessary and sufficient conditions under which a continuous bilinear functional B on $L^{p} (R^{d}) \otimes E$ , $p > 1$ , E being a separable Banach space, can be continuously extended to a linear functional on $L^{p} (R^{d}; E)$ . The extension enables a generalisation of the H-distribution concept, allowing us to obtain a (heterogeneous) velocity averaging result in the $L^{p}$ framework for any $p > 1$ .
