Abstract

In this paper, we have investigated the LRS Bianchi type-I cosmological model containing anisotropic fluid in Bimetric theory of gravitation. The Rosen’s filed equations are solved with the help of special law of variation for Hubble parameter proposed by Berman (1983). We have deduced Zeldovich universe in this theory which is accelerating in nature. Some geometrical and physical aspects of the derived model are also studied.
