SUMMARY:T&G: Bo'az Klartag (Weizmann Institute), Rigidity of Riemannian embeddings of discrete metric spaces
DESCRIPTION:Let M be a complete, connected Riemannian surface and\n\nsuppose that S is a discrete subset of M. What can we learn about M\n\nfrom the knowledge of all distances in the surface between pairs of\n\npoints of S? We prove that if the distances in S correspond to the\n\ndistances in a 2-dimensional lattice, or more generally in an\n\narbitrary net in R^2, then M is isometric to the Euclidean plane. We\n\nthus find that Riemannian embeddings of certain discrete metric spaces\n\nare rather rigid. A corollary is that a subset of Z^3 that strictly\n\ncontains a two-dimensional lattice cannot be isometrically embedded in\n\nany complete Riemannian surface. This is a joint work with M. Eilat.
