加权Bergman空间中共形映射的几何刻画

Geometric characterizations for conformal mappings in weighted Bergman spaces

Christina Karafyllia, Nikolaos Karamanlis

摘要:

证明了单位圆盘上定义的共形映射属于加权Bergman空间的充要条件是某些涉及调和测度的积分收敛。借助于这个定理,我们通过研究欧氏面积,给出了Hardy空间或加权Bergman空间中共形映射的一个几何刻划。应用这些结果,我们证明了几个后果,这样的映射,扩展已知的结果Hardy空间加权Bergman空间。此外,我们引入了一个数,这是加权Bergman空间的Hardy数的模拟。我们推导出这个数的各种表达式,从而建立了Hardy数的新结果以及Hardy空间与加权Bergman空间之间的关系。

英文摘要:

We prove that a conformal mapping defined on the unit disk belongs to a weighted Bergman space if and only if certain integrals involving the harmonic measure converge. With the aid of this theorem, we give a geometric characterization of conformal mappings in Hardy or weighted Bergman spaces by studying Euclidean areas. Applying these results, we prove several consequences for such mappings that extend known results for Hardy spaces to weighted Bergman spaces. Moreover, we introduce a number which is the analogue of the Hardy number for weighted Bergman spaces. We derive various expressions for this number and hence we establish new results for the Hardy number and the relation between Hardy and weighted Bergman spaces.
