Coxeter systems with two-dimensional Davis-Vinberg complexes

Tetsuya Hosaka

In this paper, we study Coxeter systems with two-dimensional Davis-Vinberg complexes. We show that for a Coxeter group $W$ , if $(W, S)$ and $(W, S^{'})$ are Coxeter systems with two-dim…

Reflection groups of geodesic spaces and Coxeter groups

Tetsuya Hosaka

H.S.M. Coxeter showed that a group $Γ$ is a finite reflection group of an Euclidean space if and only if $Γ$ is a finite Coxeter group. In this paper, we define {\it reflections} o…
