关于三维双曲Coxeter棱锥

On 3-dimensional hyperbolic Coxeter pyramids

Yohei Komori, Yuriko Umemoto

摘要:

利用初等平面几何对三维双曲Coxeter金字塔进行了分类,并利用Steinberg公式计算了相应Coxeter群的增长函数,得到了它们的增长率总是Perron数的结论.我们还计算了它们的双曲线体积,并将体积与它们的增长率进行了比较。最后,我们考虑几何排序的Coxeter金字塔与他们的增长率。

英文摘要:

After classifying 3-dimensional hyperbolic Coxeter pyramids by means of elementary plane geometry, we calculate growth functions of corresponding Coxeter groups by using Steinberg formula and conclude that growth rates of them are always Perron numbers. We also calculate hyperbolic volumes of them and compare volumes with their growth rates. Finally we consider a geometric ordering of Coxeter pyramids comparable with their growth rates.
