在温度为1的定向瓦片装配系统上

On the directed tile assembly systems at temperature 1

Pierre-Étienne Meunier, Damien Regnault

摘要:

我们在这里表明,在温度为1时称为定向自组装的模型无法像图灵机那样进行复杂的计算。由于这个模型可以被看作是有限自动机到2D语言的推广,逻辑方法是分两步进行。第一个是开发一个二维泵引理,第二个是使用这个泵引理来分类不同类型的可能的计算。在此之前,Meunier等人已经证明了一个泵引理,Doty等人假设存在泵引理,对不同类型的终端组装进行了分类。因此,这两篇论文的结合解决了定向温度1猜想.但并不完美事实上,由于Doty等人的工作先于Meunier等人的泵引理,因此作者假设了一个不同且更强的泵引理。然而,Doty等人的所有证明仍然与Meunier等人的泵引理相一致。为了清楚地解决定向温度1猜想,本文对这两篇文章的符号进行了协调。我们也能够给出一个最佳的描述的双周期结构,可能会出现在一些瓷砖组装系统。

英文摘要:

We show here that a model called directed self-assembly at temperature 1 is unable to do complex computations like the ones of a Turing machine. Since this model can be seen as a generalization of finite automata to 2D languages, a logical approach is to proceed in two steps. The first one is to develop a 2D pumping lemma and the second one is to use this pumping lemma to classify the different types of possible computation. Previously, Meunier at al have proven a pumping lemma and Doty et al, assuming the existence of a pumping lemma, have classified the different types of terminal assembly. Thus the combination of these two papers solves the directed temperature 1 conjecture ... but in an imperfect way. Indeed, since the work of Doty et al is anterior to the pumping lemma of Meunier et al, the authors assumed a different and stronger pumping lemma. Nevertheless, all the demonstrations made in Doty et al still hold with the pumping lemma of Meunier et al. In this paper, we harmonize the notations between these two articles in order to clearly solve the directed temperature 1 conjecture. We are also able to give an optimal description of the bi-periodic structures which may appear in some tile assembly system.
