分层拼接的上同调

Cohomology of Hierarchical Tilings

Lorenzo Sadun

摘要:

这是一本即将出版的关于非周期性秩序的书中的一章。我们去在不同版本的平铺上同调(\v切赫,模式等变,PV,商),重点是逆极限结构用于计算这些上同调。然后,我们考虑使用平铺上同调来区分空间,理解变形,并帮助理解平铺空间之间的映射。本章的重点是替换镶嵌及其推广,但其基本思想同样适用于切割和投影镶嵌以及由局部匹配规则定义的镶嵌。

英文摘要:

This is a chapter in an upcoming book on aperiodic order. We go over different versions of tiling cohomology (\v Cech, pattern-equivariant, PV, quotient) with emphasis on the inverse limit constructions used to compute these cohomologies. We then consider the uses of tiling cohomology to distinguish spaces, to understand deformations, and to help understand maps between tiling spaces. The emphasis of this chapter is on substitution tilings and their generalizations, but the underlying ideas apply equally well to cut-and-project tilings and to tilings defined by local matching rules.
