Bianchi Type-III Wet Dark Fluid Cosmological Model in Bimetric Theory

Abstract

In this paper, we have constructed a Bianchi type-III cosmological model in Rosen’s bimetric theory of gravitation (Gen. Relativ. Gravit. 4: 435, 1973) with a new equation of state for dark energy component of the universe (known as wet dark fluid). It is observed that Bianchi type-III cosmological model does not exist in bimetric theory of gravitation with dark fluid as a source of gravitation and hence only vacuum model is obtained.
