We prove that the complex interpolation space  ,  , between two weighted Bergman spaces   and   on the tube in  ,   over an irreducible symmetric cone of   is the weighted Bergman space   with  . Here,   and   where   denotes the rank of the cone. We then construct an analytic family of operators and an atomic decomposition of functions, which are related to this interpolation result.

Nous donnons une démonstration du fait que par la méthode complexe, l'espace d'interpolation  ,  , entre deux espaces de Bergman à poids   et   est l'espace de Bergman à poids   avec  , dans le tube de  ,  , au-dessus d'un cône symétrique irréductible de   Ici,  ,  , où   désigne le rang du cône. Nous construisons ensuite une famille analytique d'opérateurs et une décomposition atomique de fonctions, qui sont en relation avec ce résultat d'interpolation. Pour citer cet article : D. Békollé et al., C. R. Acad. Sci. Paris, Ser. I 337 (2003).
