利用种子瓦片强制非周期平铺:单瓦片问题

Forcing nonperiodic tilings with one tile using a seed

Bernhard Klaassen

AI总结:

本文探讨“爱因斯坦问题”的弱化形式,通过使用种子瓦片强制非周期平铺,并列举与讨论匹配规则的类型。

摘要:

所谓的“爱因斯坦问题”(一个利用著名科学家名字与德语术语“ein Stein”(意为“一块石头”)的双关语)要求找到一个单连通的原始瓦片,该瓦片仅允许非周期平铺,且无需任何匹配规则。迄今为止,研究者们仅能通过定义装饰过的原始瓦片,并利用匹配规则强制任何生成的平铺具有非周期性,从而接近这一要求。本文中,一类螺旋平铺(以及一个非螺旋示例)与爱因斯坦问题的一种较弱形式相关联,该形式使用一个或多个种子瓦片。此外,本文列出了经典类型的匹配规则,并讨论了一些新类型。

英文摘要:

The so-called "einstein problem" (a pun playing with the famous scientist's name and the German term "ein Stein" for "one stone") asks for a simply connected prototile only allowing nonperiodic tilings without need of any matching rule. So far, researchers come only close to this demand by defining decorated prototiles forcing nonperiodicity of any generated tiling using matching rules. In this paper a class of spiral tilings (and one non-spiral example) is linked to a weaker form of the einstein problem where one or several seed tiles are used. Furthermore, the classical types of matching rules are listed and some new types are discussed.
