Un analogue d'un théorème de Hardy pour la transformation de Dunkl
Comptes Rendus. Mathématique, Volume 334 (2002) no. 10, pp. 849-854.

On donne dans cette Note une généralisation d'un théorème de Hardy pour la transformation de Dunkl D sur Rd. Plus précisément, pour toutes les valeurs de a>0, b>0 et p,q∈[1,+∞], on détermine les fonctions mesurables f telles que ea||x||2fLkp(Rd) et eb||y||2D(f)Lkq(Rd), où les Lkp(Rd) sont les espaces Lp associés à la transformation de Dunkl.

In this Note we give a generalization of Hardy's theorem for the Dunkl transform D on Rd. More precisely, for all a>0, b>0 and p,q∈[1,+∞], we determine the measurable functions f such that ea||x||2fLkp(Rd) and eb||y||2D(f)Lkq(Rd), where Lkp(Rd) are the Lp spaces associated with the Dunkl transform.
