调和映射的上下阶

Lower and upper order of harmonic mappings

Arbeláez, H., Hernández, R., Sierra W

摘要:

本文定义了$\mathbb{D}$中保感调和映射的上下阶。本文将已知的关于具有正低阶的全纯函数的一些结果推广到调和函数的情形,并给出了关于具有有限高阶的函数的一些结果。此外,我们改进了有限高阶调和映射的已知偏差定理中存在等式的情形下的一个相关结果。最后给出了一些例子来说明所发展的理论。

英文摘要:

In this paper, we define both the upper and lower order of a sense-preserving harmonic mapping in $\mathbb{D}$. We generalize to the harmonic case some known results about holomorphic functions with positive lower order and we show some consequences of a function having finite upper order. In addition, we improve a related result in the case when there is equality in a known distortion theorem for harmonic mappings with finite upper order. Some examples are provided to illustrate the developed theory.
