PLANE GRAVITATIONAL WAVES IN BIMETRIC RELATIVITY

In this paper, Z = ? ? ? ? ? ? 1 1 2 1 n n n n n x x x t ? ?? ? ? ? ? ?? ?? ........ and ? ? ? ? ? ? 1 1 2 1 n n n n n t Z x x x ? ?? ?? ?? ? ?? ?? ?? ? ? ? ?? ?? ?? ?? ........ type n - dimensional plane gravitational waves are studied with the source of gravitation Cosmic strings coupled with perfect fluid distribution and domain wall coupled with an electromagnetic source in Rosen’s bimetric theory of relativity. It is shown that there is nil contribution from Comic strings coupled with perfect fluid and domain wall coupled with an electromagnetic source in this theory . Only vacuum model can be obtained
