Abstract
For p>0, let ℬp(Bn) and ℒp(Bn) denote, respectively, the p-Bloch and holomorphic p-Lipschitz spaces of the open unit ball Bn in ℂn. It is known that ℬp(Bn) and ℒ1−p(Bn) are equal as sets when p∈(0,1). We prove that these spaces are additionally norm-equivalent, thus extending known results for n=1 and the polydisk. As an application, we generalize work by Madigan on the disk by investigating boundedness of the composition operator ℭφ from ℒp(Bn) to ℒq(Bn).
