在准晶体中,无论是数学上还是物理上,都存在着两种有序概念的相互作用:局域有序和长程有序,它们通过定向作用表现出来。这两种类型的有序导致了两种非常不同的封闭概念,局域拓扑和自相关拓扑,它们在原则上是不相关的。给定R中的离散点集
In quasicrystals, both mathematical and physical, there is an interplay of two no-tions of order: a local order and a long-range order manifested through diffraction.These two types of order lead to two very different notions of closeness, the localand autocorrelation topologies, which are in principle unrelated. Given a discretepoint set in R
