Completeness of general pp-wave spacetimes and their impulsive limit
Clemens Sämann, Roland Steinbauer, Robert Švarc
We investigate geodesic completeness in the full family of pp-wave or Brinkmann spacetimes in their extended as well as in their impulsive form. This class of geometries contains t…

The global uniqueness and -regularity of geodesics in expanding impulsive gravitational waves
Jiri Podolsky, Clemens Sämann, Roland Steinbauer +1
We study geodesics in the complete family of expanding impulsive gravitational waves propagating in spaces of constant curvature, that is Minkowski, de Sitter and anti-de Sitter un…
