研究了全纯Hardy-Orlicz空间H(Phi)(Omega),其中Omega是单位球,更一般地说,是C(n)中的有限型凸域或严格伪凸域.函数Phi特别地使得对于某些p > 0,H(1)(Ω)子集H(Ω)子集H(p)(Ω)。我们开发最大的特征,原子和分子分解。然后,我们证明了涉及空间BMOA(Ω)的弱分解定理。因此,我们刻画了从H(Φ)(Ω)到H(1)(Ω)有界的Hankel算子.
We study the holomorphic Hardy-Orlicz spaces H(Phi)(Omega), where Omega is the unit ball or, more generally, a convex domain of finite type or a strictly pseudoconvex domain in C(n). The function Phi is in particular such that H(1)(Omega) subset of H(Omega) subset of H(p)(Omega) for some p > 0. We develop maximal characterizations, atomic and molecular decompositions. We then prove weak factorization theorems involving the space BMOA(Omega). As a consequence, we characterize those Hankel operators which are bounded from H(Phi)(Omega) into H(1)(Omega).
