R. S. Rane, G. C. Bhagat

Abstract


In the present study, we have studied Bianchi type-III cosmological model with perfect fluid source containing magnetic field in general theory of relativity with linearly varying variable cosmological and Gravitational constant. We have obtained the general solutions of the Einstein’s field equations for the cosmological model by assuming the circumstance of anti-stiff fluid i.e. relation between pressure and density and observed that in our derived model the Universe represents shearing, non-rotating and expanding model of the universe with big-bang starts in the midst of both scale factors is monotonically increasing function of time. The behavior of the Universe in presence of magnetic field and singularities in the model are discussed in detail. Furthermore some physical and geometrical aspects of the model are discussed.

Keywords
