Hypersurface-homogeneous space-time with anisotropic dark energy in scalar tensor theory of gravitation

The exact solutions of the field equations for Hypersurface-homogeneous space time under the assumption on the anisotropy of the fluid (dark energy) are obtained for exponential and power-law volumetric expansions in a scalar-tensor theory of gravitation proposed by Saez and Ballester (Phys. Lett. A...

Zusammenfassung:The exact solutions of the field equations for Hypersurface-homogeneous space time under the assumption on the anisotropy of the fluid (dark energy) are obtained for exponential and power-law volumetric expansions in a scalar-tensor theory of gravitation proposed by Saez and Ballester (Phys. Lett. A 113:467, 1985 ). The physical and kinematical properties of the universe have been discussed.
