摘要/Abstract

摘要：

假设 $R \in M_n({\Bbb Z})$ 为扩张矩阵和 $N$ 元数字集 ${\cal D}=\{0, a_1, a_2, \cdots, a_{N-1}\}u \equiv \{0, 1, \cdots,$ $N-1\}u \ ({\rm mod}N)$ ,这里 $u\in {\Bbb Z}^n\setminus\{0\}$ .该文主要研究由 ${\cal D}$ 和 $R$ 生成的自仿测度 $\mu_{R, {\cal D}}$ 的谱性,得到了 $\mu_{R, {\cal D}}$ 为谱测度的一个充分条件.对于一些特殊情况,得到了 $\mu_{R, {\cal D}}$ 为谱测度的一个充分必要条件,并给出其谱的具体表达式.

关键词: N元数字集, 自仿测度, 谱测度

Abstract:

Let $R \in M_n({\Bbb Z})$ be an expanding matrix and ${\cal D}=\{0, a_1, a_2, \cdots, a_{N-1}\}u \equiv \{0, 1, \cdots, N-1\}u \ ({\rm mod}N)$ be a $N$ -element digit set, where $u\in {\Bbb Z}^n\setminus\{0\}$ . In this paper, we study the spectral property of the self-affine measures $\mu_{R, {\cal D}}$ which is generated by ${\cal D}$ and $R$ , and obtain a sufficient condition such that $\mu_{R, {\cal D}}$ is a spectral measure. Moreover, for a special case, we give a necessary and sufficient condition such that $\mu_{R, {\cal D}}$ is a spectral measure, and the exact spectrum of $\mu_{R, {\cal D}}$ is given.

Key words: N-element digits, Self-affine measures, Spectral measures
