On the A-integrability of singular integral transforms
Annales de l'Institut Fourier, Volume 34 (1984) no. 2, p. 53-62

In this article we study the weak type Hardy space of harmonic functions in the upper half plane R + n+1 and we prove the A-integrability of singular integral transforms defined by Calderón-Zygmund kernels. This generalizes the corresponding result for Riesz transforms proved by Alexandrov.

Dans cet article on étudie les espaces de Hardy de type faible des fonctions harmoniques dans le demi-espace supérieur R + n+1 . On démontre la A-intégrabilité des transformées d’intégrales singulières définies par les noyaux de Calderón-Zygmund. Cela généralise un résultat analogue pour les transformées de Riesz démontré par Alexandrov.
