Résumé
Abstract

Dans cette Note, nous démontrons que tout échantillonneur moyen localisé ne peut pas être un échantillonneur stable pour $L^{2}$ , mais qu'un échantillonneur déterminant localisé existe pour $L^{2}$ .

In this Note, we show that any localized average sampler could not be a stable sampler for $L^{2}$ , but that there is a localized determining sampler for $L^{2}$ .
