We generalise the result of [11] to the (2+1) de Sitter and anti de Sitter cases. We prove that in these cases the level sets of quasi-concave times converge in the Gromov equivariant topology, when time goes to 0, to a real tree. Moreover, this limit does not depend on the choice of the time function. We also consider the problem of asymptotic behavior in the flat (n+1) dimensional case. We prove that the level sets of quasi-concave times converge in the Gromov equivariant topology, when time goes to 0, to a CAT (0) metric space. Moreover, this limit does not depend on the choice of the time function.", "revisions": [ { "version": "v1", "updated": "2015-03-21T19:45:47.000Z" } ], "analyses": { "keywords": [ "asymptotic behavior", "constant curvature space-times", "cauchy hypersurfaces", "hyperbolic spatially compact space-times", "quasi-concave times converge" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1355327 } } }
