Expanding impulsive gravitational waves | | J. Podolsky

6 Jul 1999 | | Journal: | Class.Quant.Grav. 16 (1999) 2937-2946 | | Subject: | gr-qc | | Abstract: | We explicitly demonstrate that the known solutions for expanding impulsive spherical gravitational waves that have been obtained by a "cut and paste" method may be considered to be impulsive limits of the Robinson-Trautman vacuum type N solutions. We extend these results to all the generically distinct subclasses of these solutions in Minkowski, de Sitter and anti-de Sitter backgrounds. For these we express the solutions in terms of a continuous metric. Finally, we also extend the class of spherical shock gravitational waves to include a non-zero cosmological constant. | | Source: | arXiv, gr-qc/9907022 | | Services: | Forum | Review | PDF | Favorites | |
