Web25 jun. 2013 · Let C(L) be the right‐angled Coxeter group defined by an abstract triangulation L of S2 . We show that C(L) is isomorphic to a hyperbolic right‐angled reflection group if and only if L can be realized as an acute triangulation. The proof relies on the theory of CAT(‐1) spaces. A corollary is that an abstract triangulation of S2 can be …
