Nouvelle approche du théorème de ABB
[New concept of the ABB Theorem]

This Note presents a density result of the ABB theorem type for a strong topology of a Banach space equipped with the preorder associated to a convex well-based cone. The hypothesis of compactness is relaxed. Here the technique used is based on properties of the Bishop–Phelps cone, and does not require any property of the Hening dilating cone.

Cette Note présente un résultat de densité de type (ABB) pour la topologie forte dans un espace de Banach muni du préordre associé à un cône convexe possédant une base bornée. L'hypothèse de compacité est sensiblement affaiblie et la méthode présentée ici est nouvelle à notre connaissance. Basée sur des propriétés du cône de Bishop–Phelps, elle ne nécessite pas l'utilisation des cônes de dilatation de Hening.
