The Space of Null Geodesics (and a New Causal Boundary)
The space of null geodesics, G, of a space-time, M, carries information on various aspects of the causal structure M. In this contribution, we will review the space of null geodesics, G, and some natural structures which it carries, and see how aspects of the causal structure of M are encoded there. If M is strongly causal, then G has a natural contact manifold structure, points are represented...
متن کاملGeodesics in Margulis Spacetimes
Let M be a Margulis spacetime whose associated complete hyperbolic surface Σ has compact convex core. Generalizing the correspondence between closed geodesics on M and closed geodesics on Σ, we establish an orbit equivalence between recurrent spacelike geodesics on M and recurrent geodesics on Σ. In contrast, no timelike geodesic recurs in neither forward nor backwards time.
متن کاملOn Cauchy Surfaces in Conformally Stationary Spacetimes
A criterion for a spacelike hypersurface in a conformally stationary spacetime to be a Cauchy hypersurface is given. The criterion is based on the forward and the backward completeness of a non-reversible Finsler metric associated to the hypersurface.
متن کاملAsymptotic Behavior of Geodesics in Gowdy Spacetimes
Recent work by the authors led to the development of a mathematical theory dealing with 'second– order hyperbolic Fuchsian systems', as we call them. In the present paper, we adopt a physical standpoint and discuss the implications of this theory which provides one with a new tool to tackle the Einstein equations of general relativity (under certain symmetry assumptions). Specifically, we formu...
متن کاملNote on (conformally) semi-symmetric spacetimes
We prove that conformally semi-symmetric spacetimes are actually semisymmetric. We also present a complete refined classification of the semi-symmetric spacetimes. PACS numbers: 04.20.Cv, 02.40.Ky, 04.20.Jb
