Abstract
Résumé

In this paper we show that a 1-convex (i.e., strongly pseudoconvex) manifold $X$ , with 1- dimensional exceptional set $S$ and finitely generated second homology group $H_{2} (X, ℤ)$ , is embeddable in $ℂ^{m} \times ℂ ℙ_{n}$ if and only if $X$ is Kähler, and this case occurs only when $S$ does not contain any effective curve which is a boundary.

On démontre que si $X$ est une variété fortement pseudoconvexe telle que $H_{2} (X, ℤ)$ soit de type fini et son ensemble exceptionnel $S$ de dimension 1, alors $X$ est plongeable dans $ℂ^{m} \times ℂ ℙ_{n}$ si et seulement si $X$ est une variété kählérienne; en outre cette condition est vérifiée si et seulement si $S$ ne contient aucune courbe effective qui est homologue à zéro.
