Impulsive waves in the Nariai universe
Marcello Ortaggio
A new class of exact solutions is presented which describes impulsive waves propagating in the Nariai universe. It is constructed using a six-dimensional embedding formalism adapte…

Symmetries and geodesics in (anti-)de Sitter spacetimes with nonexpanding impulsive waves
J. Podolsky, M. Ortaggio
We consider a class of exact solutions which represent nonexpanding impulsive waves in backgrounds with nonzero cosmological constant. Using a convenient 5-dimensional formalism it…
