Reflection Subgroups of Reflection Groups
P. V. Tumarkin, A. A. Felikson Independent University of Moscow
Abstract:
Let $G$ be a discrete group generated by reflections in hyperbolic or Euclidean space, and let $H\subset G$ be a finite index reflection subgroup. Suppose that the fundamental chamber of $G$ is a finite volume polytope with $k$ facets. We prove that the fundamental chamber of $H$ has at least $k$ facets.
Keywords:
reflection group, Coxeter polytope.
