• MICRO STIFF FLUID COSMOLOGICAL CONSTANT MODEL IN GENERAL RELATIVITY

Abstract

In the present paper, Bianchi type-1 micro cosmological model for perfect fluid distribution in the presence of cosmological constant is investigated in Einstein’s general relativity. For solving the field equations, the role of cosmological constant L is studied for three different cases i.e L = 0, L > 0 and L < 0. In first case i.e. when L = 0, the solutions of the field equations generate a anisotropic micro stiff fluid model of the universe. In second case,         i.e when L > 0, it is observed that the real physical model of the universe does not survive. However in third case       i.e when L < 0, the perfect fluid characterized by the equation of state p = r degenerates homogeneous, inflationary and isotropic universe.
