The Efroimsky formalism adapted to high-frequency perturbations
Otakar Svitek, Jiri Podolsky
The Efroimsky perturbation scheme for consistent treatment of gravitational waves and their influence on the background is summarized and compared with classical Isaacson's high-fr…

Geodesic motion in the Kundt spacetimes and the character of envelope singularity
Jiri Podolsky, Miroslav Belan
We investigate geodesics in specific Kundt type N (or conformally flat) solutions to Einstein's equations. Components of the curvature tensor in parallelly transported tetrads are…

A snapping cosmic string in a de Sitter or anti-de Sitter universe
J. Podolsky, J. B. Griffiths
We present and describe an exact solution of Einstein's equations which represents a snapping cosmic string in a vacuum background with a cosmological constant . The snapping of…
