Busemann [2, (27.14)] proved that every open local isometry of a compact G-space onto itself is an isometry. Thus (5.5) of the present paper generalizes this result to the case of general local isometries of convex metric continua.-Received by the editors January 5, 1981.
WitrynaGlobally, it is pretty clear that a flat disk is not isometric to the plane, but is locally, because you can cut a flat disk out of a plane with a band saw. $\endgroup$ – Ben McKay. Oct 31, 2013 at 20:58 $\begingroup$ What I have is two non-compact surfaces with the same metric, constant negative scalar, and constant negative Ricci curvatures. Witrynagauge field, in which case the solutions are locally isometric to a charged static black hole. In four dimensional General Relativity, it is well known that the spherically symmetric solutions of Einstein’s field equations in the vacuum are locally isometric to the Schwarzschild solution — this is Birkhoff’s theorem, see for example [1].
