David S. Wishart,Marcia A. Levattepersurfaces have to be spacelike, so that the metric induced on them by the . spacetime metric is . . From the mathematical point of view, this procedure allows to formulate the problem of resolution of Einstein equations as a . with constraints. From the pedestrian point

Martin Giera,Julijana Ivanisevichypersurface embedded in spacetime, we focus on spacelike hypersurfaces, which are those involved in the 3+1 formalism. We present the first and second fundamental forms, giving rise to the notions of intrinsic and extrinsic curvatures. Finally, we derive the Gauss–Codazzi equations relating the int
