A novel notion of null infinity for c-boundaries and generalized black holes
Autor: I. P. Costa e Silva, J. L. Flores, J. Herrera
Publikováno v: Journal of High Energy Physics, Vol 2018, Iss 9, Pp 1-33 (2018)
Abstract We give new definitions of null infinity and black hole in terms of causal boundaries, applicable to any strongly causal spacetime (M, g). These are meant to extend the standard ones given in terms of conformal boundaries, and use the new de

Some Remarks on Conformal Symmetries and Bartnik’s Splitting Conjecture
Autor: J. L. Flores, I. P. Costa e Silva, Jónatan Herrera
Publikováno v: Mediterranean Journal of Mathematics. 17
Inspired by the results in a recent paper by Galloway and Vega (Lett Math Phys 108(10):2285–2292, 2018), we investigate a number of geometric consequences of the existence of a timelike conformal Killing vector field in a globally hyperbolic space-

A Study in Stationary: Geometric Properties of Stationary Regions and Regularity of Their Horizons
Autor: I. P. Costa e Silva
Publikováno v: Lorentzian Geometry and Related Topics ISBN: 9783319662893
Spacetimes with stationary regions have always been among the most intensively studied ones, but by far the larger body of literature thereon has been inextricably connected with the investigation of stationary black holes arising as solutions of the

On the geodesic incompleteness of spacetimes containing marginally outer trapped surfaces
Autor: I. P. Costa e Silva
In a recent paper, Eichmair, Galloway and Pollack have proved a Gannon-Lee-type singularity theorem based on the existence of marginally outer trapped surfaces (MOTS) on noncompact initial data sets for globally hyperbolic spacetimes. This result req

Extremal surfaces and the rigidity of null geodesic incompleteness
Autor: J. L. Flores, I. P. Costa e Silva
Publikováno v: Classical and Quantum Gravity. 32:055010
An important, if relatively less well known aspect of the singularity theorems in Lorentzian geometry, is to understand how their conclusions fare upon weakening or suppression of one or more of their hypotheses. Then, theorems with modified conclusi
