Evolution of high-frequency gravitational waves in some cosmological models
arXiv:gr-qc/0609066 · doi:10.1007/s10582-006-0449-z
Abstract
We investigate Isaacson's high-frequency gravitational waves which propagate in some relevant cosmological models, in particular the FRW spacetimes. Their time evolution in Fourier space is explicitly obtained for various metric forms of (anti--)de Sitter universe. Behaviour of high-frequency waves in the anisotropic Kasner spacetime is also described.
