On the Rigidity Theorem for Spacetimes with a Stationary Event Horizon or a Compact Cauchy Horizon
We consider smooth electrovac spacetimes which represent either (A) an asymptotically flat, stationary black hole or (B) a cosmological spacetime with a compact Cauchy horizon ruled by closed null geodesics. The black hole event horizon or, respectively, the compact Cauchy horizon of these spacetimes is assumed to be a smooth null hypersurface which is non-degenerate in the sense that its null ...
متن کاملa cauchy-schwarz type inequality for fuzzy integrals
نامساوی کوشی-شوارتز در حالت کلاسیک در فضای اندازه فازی برقرار نمی باشد اما با اعمال شرط هایی در مسئله مانند یکنوا بودن توابع و قرار گرفتن در بازه صفر ویک می توان دو نوع نامساوی کوشی-شوارتز را در فضای اندازه فازی اثبات نمود.
15 صفحه اولOn rigidity of spacetimes with a compact Cauchy horizon
There is a great variety of solutions of Einstein’s equation which contain a smooth compact Cauchy horizon. However, all of these spacetimes can be considered as being generalizations of the Taub-NUT solution. In these spacetimes, the Cauchy horizon separates the globally hyperbolic region from a region which contains closed timelike curves. It is a common feature of all of these spacetimes tha...
متن کاملCauchy horizon singularity without mass inflation.
A perturbed Reissner-Nordström-de Sitter solution is used to emphasize the nature of the singularity along the Cauchy horizon of a charged spherically symmetric black hole. For these solutions, conditions may prevail under which the mass function is bounded and yet the curvature scalar R αβγδ R αβγδ diverges.
متن کاملStructure of the Cauchy Horizon Singularity
We study the Cauchy horizon (CH) singularity of a spherical charged black hole perturbed nonlinearly by a self-gravitating massless scalar field. We show numerically that the singularity is weak both at the early and at the late sections of the CH, where the focusing of the area coordinate r is strong. In the early section the metric perturbations vanish, and the fields behave according to pert...
