چکیده
Given a globally hyperbolic spacetime M , we show the existence of a smooth spacelike Cauchy hypersurface S and, thus, a global diffeomorphism between M and R × S.

Causal hierarchy of spacetimes, temporal functions and smoothness of Geroch’s splitting. A revision
In the heroic epoch of Causality Theory, the problems concerning the smoothability of time functions and Cauchy hypersurfaces remained as unanswered folk questions. Just recently solved, our aim is to discuss the state of the art on this topic, including self-contained proofs for questions on causally continuous, stably causal and globally hyperbolic spacetimes.
متن کاملRigid Singularity Theorem in Globally Hyperbolic Spacetimes
30 years ago, Penrose-Hawking have shown that spacetimes are geodesically incomplete under some physically reasonable conditions [1] [2] [3] [4]. The generic condition is the key assumption to induce singularities rigidly. Geroch improved these theorems with “no observer horizon” condition in place of the generic condition for the spatially closed universe [5,6]. Here, the “no observer horizon”...
متن کاملSmooth globally hyperbolic splittings and temporal functions
Geroch’s theorem about the splitting of globally hyperbolic spacetimes is a central result in global Lorentzian Geometry. Nevertheless, this result was obtained at a topological level, and the possibility to obtain a metric (or, at least, smooth) version has been controversial since its publication in 1970. In fact, this problem has remained open until a definitive proof, recently provided by t...
متن کاملMaximum Principles for Null Hypersurfaces and Null Splitting Theorems
The geometric maximum principle for smooth (spacelike) hypersurfaces, which is a consequence of Alexandrov’s [1] strong maximum for second order quasilinear elliptic operators, is a basic tool in Riemannian and Lorentzian geometry. In [2], extending earlier work of Eschenburg [7], a version of the geometric maximum principle in the Lorentzian setting was obtained for rough (C) spacelike hypersu...
متن کاملSmoothness of Time Functions and the Metric Splitting of Globally Hyperbolic Spacetimes
The folk questions in Lorentzian Geometry which concerns the smoothness of time functions and slicings by Cauchy hypersurfaces, are solved by giving simple proofs of: (a) any globally hyperbolic spacetime (M, g) admits a smooth time function T whose levels are spacelike Cauchy hyperfurfaces and, thus, also a smooth global splitting M = R×S, g = −β(T , x)dT 2 + ḡT , (b) if a spacetime M admits a...
