At the same time, logλ(w) is the translation length of w in the Hilbert metric on K, so this … WebOur main interest will be hyperbolic and higher-rank Coxeter groups. For such groups, we observe that the Hilbert metric on the interior of the Tits cone K is well-deﬁned and invariant, and passes to the space of rays PK . Thus (PK ,d K) serves as a generalization of the Klein model for hyperbolic space to the case of higher-rank Coxeter groups.
