$\mathbb{C}^k$的整映射半群的动力学

Dynamics of semigroups of entire maps of $\mathbb{C}^k$

Sayani Bera, Ratna Pal

摘要:

本文研究了$\mathbb{C}^k,\; k \ge 2$的一类全纯自同态的Fatou集和朱利亚集的一些基本性质.我们特别感兴趣的研究这些集的半群生成的各种类的全纯自同态的$\mathbb{C}^k,\; k \ge 2.$我们证明了,如果朱利亚集的半群$G$生成的最大通秩$k$在$\mathbb{C}^k$的自同态包含一个孤立点,那么$G$必须包含一个元素,共轭的上三角自同构的$\mathbb{C}^k.$这推广了Fornaess-Sibony定理。其次,我们定义了半群的回归域,并在一定条件下给出了这类域的刻画。

英文摘要:

The goal of this paper is to study some basic properties of the Fatou and Julia sets for a family of holomorphic endomorphisms of $\mathbb{C}^k,\; k \ge 2$. We are particularly interested in studying these sets for semigroups generated by various classes of holomorphic endomorphisms of $\mathbb{C}^k,\; k \ge 2.$ We prove that if the Julia set of a semigroup $G$ which is generated by endomorphisms of maximal generic rank $k$ in $\mathbb{C}^k$ contains an isolated point, then $G$ must contain an element that is conjugate to an upper triangular automorphism of $\mathbb{C}^k.$ This generalizes a theorem of Fornaess-Sibony. Secondly, we define recurrent domains for semigroups and provide a description of such domains under some conditions.
