Dans cette Note, nous démontrons que tout échantillonneur moyen localisé ne peut pas être un échantillonneur stable pour , mais qu'un échantillonneur déterminant localisé existe pour .
In this Note, we show that any localized average sampler could not be a stable sampler for , but that there is a localized determining sampler for .
