Sur , n⩾1 et n≠2, on établit l'existence de meilleurs constantes dans les inégalités de Sobolev pour les dérivées fractionelles d'ordre supérieur. Soit s un reel positif. Pour n>2s et toute fonction vérifie l'inégalité suivante
On , n⩾1 and n≠2, we prove the existence of a sharp constant for Sobolev inequalities with higher fractional derivatives. Let s be a positive real number. For n>2s and any function satisfies
