Résumé
Abstract

Soit $K$ un compact d’un ouvert $V$ dans $C^{n}$ . On démontre l’existence d’un voisinage $U$ de $K$ qui satisfait la condition suivante : si $f$ est holomorphe sur $V$ et s’il existe une suite des polynomes qui approchent $f$ uniformément sur un voisinage ouvert $U_{f}$ de $K$ , il existe une suite de polynômes qui approchent $f$ uniformément sur $U$

Let $K$ be an compact subset of an open set $V$ in $C^{n}$ . We show the existence of an open neighborhood $U$ of $K$ satisfying the following condition : if $f$ is holomorphic in $V$ and if there exists a sequence of polynomials which approximate $f$ uniformly in some open neighborhood $U_{f}$ of $K$ , there exists a sequence of polynomial which approximate $f$ uniformly in $U$ .
