| Summary: | Gravitational waves in the Friedmann-Robertson-Walker spacetime are decomposed
in various ways. The decomposition is held with asumption that this treatment
is far away from the source and coordinat choosen is geodesic slicing. Fisrt
Decompositon is done in the vacum solution. Second decomposition is done by gravitational
waves extraction on the Robertson-Walker metric background. Moncrief
gauge-invariant function is used for the extraction. Third decomposition is done by
decomposition 3+1 ADM equations. The ways decomposition have been done can
show waveform from gravitational waves in the FRW spacetime background. |
