{wiki=Alexandrov's_uniqueness_theorem}
Alexandrov's uniqueness theorem is a fundamental result in the theory of geometric measure and Riemannian geometry, particularly concerning the uniqueness of hyperbolic metrics in certain settings. Named after the Russian mathematician P.S. Alexandrov, the theorem primarily deals with the properties of spaces with non-positive curvature.
