Sampling in a weighted Sobolev space
[Échantillonage dans un espace de Sobolev avec poids]
Comptes Rendus. Mathématique, Volume 350 (2012) no. 21-22, pp. 941-944.

Nous démontrons que toute fonction f dans un certain espace de Sobolev avec poids est complètement determinée par un échantillon {f(tn)}nZ{fˆ(λk)}kZ sur des convenables suites croissantes {tn}nZ et {λn}nZ, tendant vers ±∞ lentement, quand n±.

We show that functions f in some weighted Sobolev space are completely determined by time-frequency samples {f(tn)}nZ{fˆ(λk)}kZ along appropriate slowly increasing sequences {tn}nZ and {λn}nZ tending to ±∞ as n±.
