On caractérise la -convexité et la -concavité d’un treillis de Banach à l’aide de la factorisation des opérateurs de multiplication de dans à travers l’espace . Cette caractérisation est utilisée pour calculer le type de concavité des espace de Lorentz.
-convexity and -concavity of a Banach lattice are characterized by factorization of multiplication operators from into through . This characterization is applied to calculate the concavity type of Lorentz spaces.
