Abstract:The exact solutions of the Einstein field equations for dark energy in Kantowski-Sachs metric under the assumption on the anisotropy of the fluid are obtained for exponential and power-law volumetric expansions. The isotropy of the fluid, space and expansion are examined.PACS (2008)

The anisotropic nature of the dark energy for Bianchi type-VI 0 space time is discussed. The exact solution of the Einstein field equations under the assumption on the anisotropy of the fluid are obtained for exponential and power-law volumetric expansions. The isotropy of the fluid, space and expansion are examined.

Abstract:In this paper we have studied the KantowskiSachs cosmological model with the quark and strange quark matter in the f (R) theory of gravity. The general solutions of the eld equations are obtained by assuming the physical condition shear scalar σ is proportional to scalar expansion θ, which leads to the relation B = A n between metric coe cients B and A. The physical and geometrical aspects of the model are also discussed.
