Boundedness of Hankel operators on H1(Bn)
[Continuité de l'opérateur de Hankel sur H1(Bn)]
Comptes Rendus. Mathématique, Tome 344 (2007) no. 12, pp. 749-752.

On démontre que l'opérateur de Hankel hb associé au projecteur de Szegö sur la boule unité s'étend continûment à l'espace de Hardy H1(Bn) si et seulement si b est à oscillation moyenne logarithmique sur la sphère unité.

We prove that the Hankel operator hb associated to the Szegö projection on the unit ball Bn is bounded on the Hardy space H1(Bn) if and only if its symbol b has logarithmic mean oscillation on the unit sphere.
