边界Schwarz引理的极值函数

Extremal functions of boundary Schwarz lemma

Guangbin Ren, Xieping Wang

摘要:

本文利用解析半群方法和Julia-Carathéodory定理对开单位圆盘$\mathbb D\subset \mathbb C$上的单叶全纯自映射给出了Frolova等人的经典边界Schwarz引理的一个尖锐版本的初等证明.我们的方法在求边界Schwarz引理中的不等式的极值函数方面有其特殊的优点。

英文摘要:

In this paper, we present an alternative and elementary proof of a sharp version of the classical boundary Schwarz lemma by Frolova et al. with initial proof via analytic semigroup approach and Julia-Carathéodory theorem for univalent holomorphic self-mappings of the open unit disk $\mathbb D\subset \mathbb C$. Our approach has its extra advantage to get the extremal functions of the inequality in the boundary Schwarz lemma.
