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

Algebraic structure of Robinson-Trautman and Kundt geometries in arbitrary dimension
Jiri Podolsky, Robert Svarc
We investigate the Weyl tensor algebraic structure of a fully general family of D-dimensional geometries that admit a non-twisting and shear-free null vector field k. From the coor…
