## Statement

If a 3-manifold $\Sigma$ (or more generally a smooth manifold of dimension $\geq 3$) admits the structure of a hyperbolic manifold of finite volume, then this structure is unique up to isometry, and in fact it is uniquely determined already by the fundamental group $\pi_1(\Sigma)$.

(Mostow 68).
