压缩函数的性质与有界域的几何

Properties of squeezing functions and geometry of bounded domains

Fusheng Deng, Qi'an Guan, Liyou Zhang

摘要:

本文继续研究压缩函数的性质和有界域的几何。研究了有界域序列的压缩函数的极限。利用压缩函数比较了有界域上的内禀正形式和度量。为了研究压缩函数的边界表现,我们引入了(内禀)球捏半径的概念,并据此给出了压缩函数的边界估计。最后,我们利用这些结果研究了一些有趣的域的几何和解析性质,包括平面域,Cartan-Hartogs域,以及非凸的强伪凸Reinhardt域.作为推论,所有Cartan-Hartogs域都是齐次正则的,即,它们的压缩函数具有正的下界。

英文摘要:

In this article we continue the study of properties of squeezing functions and geometry of bounded domains. The limit of squeezing functions of a sequence of bounded domains is studied. We give comparisons of intrinsic positive forms and metrics on bounded domains in terms of squeezing functions. To study the boundary behavior of squeezing functions, we introduce the notions of (intrinsic) ball pinching radius, and give boundary estimate of squeezing functions in terms of these datum. Finally, we use these results to study geometric and analytic properties of some interesting domains, including planar domains, Cartan-Hartogs domains, and a strongly pseudoconvex Reinhardt domain which is not convex. As a corollary, all Cartan-Hartogs domains are homogenous regular, i.e., their squeezing functions admit positive lower bounds.
