产生离散反射群的球单形
Spherical simplices generating discrete reflection groups
摘要:
令$P$是$S^n$中的单形,并且$G_P$是由关于$P$的小平面的反射生成的群。我们感兴趣的情况下,当组$G_P$是离散的。在这种情况下,我们说$G$生成离散反射群$G_P$。我们开发的标准,单形产生离散反射群。我们还描述了所有不可分解的球面单形产生离散反射群。
英文摘要:
Let $P$ be a simplex in $S^n$ and $G_P$ be a group generated by the reflections with respect to the facets of $P$. We are interested in the case when the group $G_P$ is discrete. In this case we say that $G$ generates the discrete reflection group $G_P$. We develop the criteria for a simplex generating a discrete reflection group. We also describe all indecomposable spherical simplices generating discrete reflection groups.
