Abstract
Résumé

We prove that the Hankel operator $h_{b}$ associated to the Szegö projection on the unit ball $B^{n}$ is bounded on the Hardy space $H^{1} (B^{n})$ if and only if its symbol b has logarithmic mean oscillation on the unit sphere.

On démontre que l'opérateur de Hankel $h_{b}$ associé au projecteur de Szegö sur la boule unité s'étend continûment à l'espace de Hardy $H^{1} (B^{n})$ si et seulement si b est à oscillation moyenne logarithmique sur la sphère unité.
