论文摘要
我们表明,对于塞勒姆数字$β$ $ d $的$β$,存在一个正常数$ c(d)$,即$β^m $是整数$ m $的自然密度$ \ ge c(d)$的帕里号。此外,我们显示$ c(6)> 1/2 $,并讨论与尺寸$ 4 $的离散旋转的关系。
We show that for a Salem number $β$ of degree $d$, there exists a positive constant $c(d)$ that $β^m$ is a Parry number for integers $m$ of natural density $\ge c(d)$. Further, we show $c(6)>1/2$ and discuss a relation to the discretized rotation in dimension $4$.
