Phys. Rev. Lett. 59, 2389–2392 (1987)Parametrization of the Space of Solutions of Einstein's EquationsReceived 22 June 1987; published in the issue dated 23 November 1987 An explicit parametrization is obtained of the set of all space-time solutions of Einstein's equations which are globally hyperbolic and contain a compact spatial hypersurface with constant mean curvature. This parametrization is based upon the conformal treatment of the initial-value problem for Einstein's equations, which is studied by the method of sub and super solutions for quasilinear elliptic partial differential equations. The Yamabe-Aubin-Trudinger-Schoen classification of conformal classes of Riemannian metrics plays a key role. © 1987 The American Physical Society URL:
