Résumé
Abstract

On considère un théorème de plongement bilinéaire pour une classe des opérateurs de Schrödinger sur $L^{p}$ . Le résultat ne depend pas de dimension et il est p-linéaire. On fait une esquisse de la démonstration basée sur trois observations concernant la fonction de Bellman spécifique.

We discuss bilinear embedding theorems for a certain class of Schrödinger operators on $L^{p}$ . The obtained estimates are dimension-free and linear in p. We outline a uniform proof of the theorem which relies on establishing three crucial properties of the concrete Bellman function we consider.
