Cesar A. Guerrero,William H. Belletric on . and . : .×ℝ → ℝ a function), which generalize classical plane waves, are revisited. Our study covers causality (causal ladder, non-existence of horizons), geodesic completeness, geodesic connectedness and existence of conjugate points. Appropriate mathematical tools for each problem are e

Fernando Molina,Alvaro A. Figueroam general relativity of Beig and Ó Murchadha. It is shown that the algebra of asymptotic Killing symmetries, defined with respect to a given foliation of the spacetime, depends on the fall-off. rate of the metric. It is only the Lorentz Lie algebra for slow fall-off, but it is the Poincaré algebra f

Christoph Bauer,Jens-Eric von Düsterlhotations of these equations. We illustrate this in two examples, the numerical evolution of “bubble” and single black hole space-times. The former is chosen to demonstrate how accurate numerical solutions can answer open questions and even reveal unexpected phenomena. The latter illustrates some of t
