Non-Static Plane Symmetric Magnetized Cosmological Models in Bimetric Theory of Gravitation

Abstract

Non-static plane symmetric cosmological models are investigated in Rosen's [Gen.Rel.Grav.Vol.4 (1973) 435] bimetric theory of gravitation in the context of cosmic string coupled with electromagnetic field, perfect fluid coupled with electromagnetic field and mesonic perfect fluid coupled with electromagnetic field. It is observed that the plane symmetric non-static cosmological model exists  in 1^st case  but  vacuum and  false vacuum models are established in 2^nd case. The result found in 3^rd case leads to the result already obtained and studied by Mohanty and Sahoo [Czech. J.Phy. 52 (2002)1041]. It is interesting to note that there is no contribution to electromagnetic field in both 2^nd and 3^rd case. Some physical and geometrical behavior of the exhibited models is also discussed.
