We establish several optimal L 2 extension theorems of openness type on weakly pseudoconvex Kähler manifolds. We prove a product property for certain minimal L 2 extensions, which generalizes the product property of Bergman kernels. We describe a different approach to the Suita conjecture and its generalizations, which is based on a log-concavity for certain minimal L 2 integrals.

Nous établissons quelques théorèmes d’extension optimaux L 2 pour les formes ouvertes sur les variété Kähler faiblement pseudoconvexes. Nous prouvons les propriétés de produit de certaines extensions minimales de L 2 , qui généralisent les propriétés de produit du noyau Bergman. Sur la base de la concavité logarithmique de certaines intégrales minimales de L 2 , nous donnons une méthode différente pour la conjecture de Suita et son extension.
