一类新的全纯齐性正则域及关于压缩函数的若干问题

A new family of holomorphic homogeneous regular domains and some questions on the squeezing function

Gautam Bharali

摘要:

我们重新审视的现象,对于某些域$D$,如果压缩函数$s_D$连续延伸到一个点$p\in \partial{D}$值$1$,那么$\partial{D}$是强伪凸周围$p$。在$\mathbb{C}^2$中,我们提出了较弱的条件下,后者的结论。在另一个方向,我们表明,有界域$D\Subset \mathbb{C}^n$,$n\geq 2$,承认大$\partial{D}$ -开放的子集$\mathscr{O}\subset \partial{D}$,使$s_D\to 0$接近任何点在$\mathscr{O}$。这对于平面域是不可能的。我们提出一些与这些现象有关的问题。但本文的核心结果证明了一类新的全纯齐性正则域。我们通过一个家庭的例子,如何丰富的域满足这个结果的条件。

英文摘要:

We revisit the phenomenon where, for certain domains $D$, if the squeezing function $s_D$ extends continuously to a point $p\in \partial{D}$ with value $1$, then $\partial{D}$ is strongly pseudoconvex around $p$. In $\mathbb{C}^2$, we present weaker conditions under which the latter conclusion is obtained. In another direction, we show that there are bounded domains $D\Subset \mathbb{C}^n$, $n\geq 2$, that admit large $\partial{D}$-open subsets $\mathscr{O}\subset \partial{D}$ such that $s_D\to 0$ approaching any point in $\mathscr{O}$. This is impossible for planar domains. We pose a few questions related to these phenomena. But the core result of this paper identifies a new family of holomorphic homogeneous regular domains. We show via a family of examples how abundant domains satisfying the conditions of this result are.
