由$P(x)=x^4-x^3-x^2-x-1$生成的$\RR \times \CC$中Rauzy分形集的边界

摘要:

研究了由多项式$P(x) = x^4-x^3-x^2-x-1$生成的三维Rauzy分形${\mathcal E} \subset \RR \times \CC$的边界。明确给出了刻画${\mathcal E}$边界的有限自动机。因此,我们证明了集合${\mathcal E}$有18个邻域,其中6个邻域与中心瓦片${\mathcal E}$相交于一点。我们的构造表明,边界是由一个迭代函数系统从2紧集开始。

英文摘要:

We study the boundary of the 3-dimensional Rauzy fractal ${\mathcal E} \subset \RR \times \CC$ generated by the polynomial $P(x) = x^4-x^3-x^2-x-1$. The finite automaton characterizing the boundary of ${\mathcal E}$ is given explicitly. As a consequence we prove that the set ${\mathcal E}$ has 18 neighborhoods where 6 of them intersect the central tile ${\mathcal E}$ in a point. Our construction shows that the boundary is generated by an iterated function system starting with 2 compact sets.
