Soit une suite de points du demi-plan supérieur ; si, pour tel que , et pour toute suite dans il existe une fonction , intégrale de poisson d’une fonction de qui vérifie :
alors nous montrons que est une suite d’interpolation pour . De même, si on fait l’hypothèse qu’il existe une solution , intégrale de Poisson d’une fonction de BMO qui vérifie avec et dans , est encore une suite d’interpolation pour .
Un théorème un peu plus général est prouvé et on donne un contre-exemple dans le cas où .
Let be a sequence in the upper half plane. If and if
has solution in the class of Poisson integrals of functions for any sequence , then we show that is an interpolating sequence for . If , has solution in the class of Poisson integrals of BMO functions whenever , then is again an interpolating sequence for . A somewhat more general theorem is also proved and a counterexample for the case is described.
