关于拟对称同胚的维数扭曲

On the dimension distortions of quasi-symmetric homeomorphisms

Shengjin Huo

摘要:

本文首先推广了Bishop和Steger [PSL(2,R)中的表示论刚性]的一个结果.数学学报,170,(1993),121-149]证明了对于发散型非格Fuchsian群$G$,若$h$是实轴$\mathbb{R}$的拟对称同胚,则对应于$G$的拟共形紧变形.然后对于任何$E\subset \mathbb{R}$,我们有max(dim $E$,dim $h(\mathbb{R}\setminus E))=1$ .进一步证明了Bishop和Steger的结果不适用于所有“$d$ -dimensional jungle gym”(d为任意正整数)的覆叠群,推广了Gönye的结果[ Differentiability of quasi-conformal maps on the jungle gym. Trans.Amer.Math.Soc.19359(2007),9-32],其中作者讨论了“$1$ -维丛林体操”的情况。

英文摘要:

In this paper, we first generalize a result of Bishop and Steger [Representation theoretic rigidity in PSL(2, R). Acta Math., 170, (1993), 121-149] by proving that for a Fuchsian group $G$ of divergence type and non-lattice, if $h$ is a quasi-symmetric homeomorphism of the real axis $\mathbb{R}$ corresponding to a quasi-conformal compact deformation of $G$. Then for any $E\subset \mathbb{R}$, we have max(dim$E$, dim$h(\mathbb{R}\setminus E))=1$. Furthermore, we showed that Bishop and steger's result does not hold for the covering groups of all '$d$-dimensional jungle gym' (d is any positive integer) which generalizes Gönye's results [ Differentiability of quasi-conformal maps on the jungle gym. Trans. Amer. Math. Soc. Vol 359 (2007), 9-32] where the author discussed the case of '$1$-dimensional jungle gym'.
