Query: Cluster algebras and triangulated orbifolds   We construct geometric realization for non-exceptional mutation-finite
cluster algebras by extending the theory of Fomin and Thurston to
skew-symmetrizable case. Cluster variables for these algebras are renormalized
lambda lengths on certain hyperbolic orbifolds. We also compute growth rate of
these cluster algebras, provide positivity of Laurent expansions of cluster
variables, and prove sign-coherence of c-vectors.
