一类一维置换镶嵌系统的纯离散谱

Pure discrete spectrum for a class of one-dimensional substitution tiling systems

Marcy Barge

摘要:

证明了如果一个本原的非周期置换在首字母上是单射的,在尾字母上是常数的,并且具有Pisot膨胀,则对应的平铺空间上的R作用具有纯离散谱.因此,β a Pisot简单帕里数的所有β-替换都有具有纯离散谱的平铺动力系统,例如,从Jacobi-Perron和Brun连分数展开中产生的Pisot系统也是如此。

英文摘要:

We prove that if a primitive and non-periodic substitution is injective on initial letters, constant on final letters, and has Pisot inflation, then the R-action on the corresponding tiling space has pure discrete spectrum. As a consequence, all beta-substitutions for beta a Pisot simple Parry number have tiling dynamical systems with pure discrete spectrum, as do the Pisot systems arising, for example, from the Jacobi-Perron and Brun continued fraction expansions.
