极值点方法与单叶调和映射

Extreme points method and univalent harmonic mappings

Y. Abu Muhanna, S. Ponnusamy

摘要:

本文考虑单位圆盘$\ID$上定义的所有保义复值调和映射类$f=h+\bar {g}$,其正规化为$h(0)=h'(0)-1=0$,$g(0)=g'(0)=0$具有第二复伸缩$ω:\,\ID\rightarrow \ID$,$g'(z)=ω(z)h'(z)$ .本文给出了$h$和$ω$上包含调和映射$f=h+\bar {g}$在$\ID$上的单叶性的充分条件.

英文摘要:

We consider the class of all sense-preserving complex-valued harmonic mappings $f=h+\bar {g}$ defined on the unit disk $\ID$ with the normalization $h(0)=h'(0)-1=0$ and $g(0)=g'(0)=0$ with the second complex dilatation $ω:\,\ID\rightarrow \ID$, $g'(z)=ω(z)h'(z)$. In this paper, the authors determine sufficient conditions on $h$ and $ω$ that would imply the univalence of harmonic mappings $f=h+\bar {g}$ on $\ID$.
