阿贝尔群之外的线性重复性
Linear repetitivity beyond abelian groups
AI总结:
本文将线性重复 Delone 集包络的唯一遍历性推广到阿贝尔群之外,并借助 Ornstein–Weiss 拟铺砌与次可加收敛定理,在可和幺模 lcsc 群中建立缓增重复条件下的相应结论。
摘要:
我们证明,多项式增长群中的线性重复加权 Delone 集具有唯一遍历的包络。这一结果尤其适用于姊妹论文 arXiv:2109.15210 中利用符号替换方法所构造的齐次 Lie 群中的线性重复加权 Delone 集。更一般地,利用 Ornstein–Weiss 的拟铺砌方法,我们在一个称为缓增重复性的新重复性条件下,确立了可和幺模 lcsc 群中加权 Delone 集包络的唯一遍历性。为此,我们建立了一个一般的次可加收敛定理;该定理还可应用于 Banach 密度的存在性,以及 Cayley 图上有限跃迁范围算子谱分布函数的一致逼近。
英文摘要:
We show that linearly repetitive weighted Delone sets in groups of polynomial growth have a uniquely ergodic hull. This result applies in particular to the linearly repetitive weighted Delone sets in homogeneous Lie groups constructed in the companion paper arXiv:2109.15210 using symbolic substitution methods. More generally, using the quasi-tiling method of Ornstein-Weiss, we establish unique ergodicity of hulls of weighted Delone sets in amenable unimodular lcsc groups under a new repetitivity condition which we call tempered repetitivity. For this purpose, we establish a general sub-additive convergence theorem, which also has applications concerning the existence of Banach densities and uniform approximation of the spectral distribution function of finite hopping range operators on Cayley graphs.
