自仿射集与多带自动机的不可判定性

Undecidable properties of self-affine sets and multi-tape automata

Timo Jolivet, Jarkko Kari

摘要:

本文研究了一些来自分形几何的对象的拓扑性质的可判定性。证明了二维图定向迭代函数系统定义的集合内部为空是不可判定的。这些结果是通过研究与多带自动机相关的一类特殊的自仿射集得到的。我们首先建立了这样的自动机的语言理论的一些属性的不可判定性,然后转化为不可判定性的结果,其相关的自仿射集。

英文摘要:

We study the decidability of the topological properties of some objects coming from fractal geometry. We prove that having empty interior is undecidable for the sets defined by two-dimensional graph-directed iterated function systems. These results are obtained by studying a particular class of self-affine sets associated with multi-tape automata. We first establish the undecidability of some language-theoretical properties of such automata, which then translate into undecidability results about their associated self-affine sets.
