Mean periodic functions on phase space and the Pompeiu problem with a twist
Annales de l'Institut Fourier, Tome 45 (1995) no. 4, pp. 1007-1035.

Si f est une fonction moyenne périodique, tempérée, sur le groupe d’Heisenberg réduit, alors le sous-espace fermé engendré par f, invariant par translation et rotation, contient une fonction sphérique élémentaire. À l’aide d’un théorème de Paley-Wiener pour la transformation de Fourier-Weyl, nous formulons une conjecture pour les fonctions moyenne périodiques quelconques.

We show that when f is a mean periodic function of tempered growth on the reduced Heisenberg group then the closed translation and rotation invariant subspace generated by f contains an elementary spherical function. Using a Paley-Wiener theorem for the Fourier-Weyl transform we formulate a conjecture for arbitrary mean periodic functions.
