Pointwise multipliers and corona type decomposition in BMOA
Annales de l'Institut Fourier, Tome 46 (1996) no. 1, pp. 111-137.

Dans cet article nous obtenons plusieurs caractérisations des multiplicateurs ponctuels de l’espace BMOA dans la boule unité B de n . De plus, si g 1 ,...,g m sont des fonctions holomorphes dans B nous démontrons que l’application M g (f)(z)= j=1 m g j (z)f j (z) envoie BMOA×...×BMOA sur BMOA si et seulement si les fonctions g j sont multiplicateurs de l’espace BMOA et satisfont j=1 m |g j (z)|δ>0.

In this paper we obtain several characterizations of the pointwise multipliers of the space BMOA in the unit ball B of n . Moreover, if g 1 ,...,g m are holomorphic functions on B, we prove that M g (f)(z)= j=1 m g j (z)f j (z) maps BMOA×...×BMOA onto BMOA if and only if the functions g j are multipliers of the space BMOA and satisfy j=1 m |g j (z)|δ>0.
