双曲平面上的一类弱泛元胞自动机

A family of weakly universal cellular automata in the hyperbolic plane with two states

Maurice Margenstern

摘要:

本文对双曲平面上的所有网格构造了一族弱泛旋转不变元胞自动机$\{p,3\}$,其中$\{p,3\}$为$p\geq 13$。该方案对$p\geq 17$和$13\leq p<17$都是通用的,我们给出了$p=13$的元胞自动机,这就足够了.此外,这个家庭的一个重要性质是,一组细胞的细胞自动机,这是受变化实际上是一个平面集。真正平面结构的$p<13$的问题仍然是开放的。对于$p=7$,最好的结果是四种状态,并且是由同一作者获得的。

英文摘要:

In this paper, we construct a family of weakly universal rotation invariant cellular automaton for all grids $\{p,3\}$ of the hyperbolic plane for $p\geq 13$. The scheme is general for $p\geq 17$ and for $13\leq p<17$, we give such a cellular automaton for $p=13$, which is enough. Also, an important property of this family is that the set of cells of the cellular automaton which are subject to changes is actually a planar set. The problem for $p<13$ for a truly planar construction is still open. The best result, for $p=7$, is four states and was obtained by the same author.
