关于压缩函数的一个注记

A note on the squeezing function

Alexander Yu. Solynin

摘要:

$\mathbb{C}$上的压缩问题可以表述如下。假设$Ω$是包含原点$z=0$的单位圆盘$\mathbb{D}$中的多连通域。一个保持原点不变的单射全纯函数$f:Ω\to \mathbb{D}$可以将$Ω$的边界从原点推多远?本文讨论了Ng,Tang和Tsai(Math.Anal. 2020)和Gumenyuk和Roth(arXiv:2011.13734,2020),也证明了一些新的结果,使用我们以前的论文(Zapiski Nauchn. Sem等POMI 1993)。

英文摘要:

The squeezing problem on $\mathbb{C}$ can be stated as follows. Suppose that $Ω$ is a multiply connected domain in the unit disk $\mathbb{D}$ containing the origin $z=0$. How far can the boundary of $Ω$ be pushed from the origin by an injective holomorphic function $f:Ω\to \mathbb{D}$ keeping the origin fixed? In this note, we discuss recent results on this problem obtained by Ng, Tang and Tsai (Math. Anal. 2020) and by Gumenyuk and Roth (arXiv:2011.13734, 2020) and also prove few new results using a method suggested in one of our previous papers (Zapiski Nauchn. Sem. POMI 1993).
