Yohei Komori, Tomoshige Yukita

摘要:

研究了三维双曲空间中理想Coxeter群的增长率集G,G由大于1的实代数整数组成。我们证明了(1)G是上无界的且有极小值,(2)G的任意元素是Perron数,(3)具有$n$生成元的理想Coxeter群的增长率位于闭区间$[n-3, n-1]$内.

英文摘要:

We study the set G of growth rates of of ideal Coxeter groups in hyperbolic 3-space which consists of real algebraic integers greater than 1. We show that (1) G is unbounded above while it has the minimum, (2) any element of G is a Perron number, and (3) growth rates of of ideal Coxeter groups with $n$ generators are located in the closed interval $[n-3, n-1]$.
