Bianchi type-V solutions with varying G and Λ: The general case
International Journal of Geometric Methods in Modern Physics, 2020The homogeneous and anisotropic Bianchi type-V cosmological model with variable gravitational and cosmological “constants” with a general (nonstiff) perfect fluid is investigated. The Einstein field equations (EFEs) are numerically integrated with the fourth-order Runge–Kutta method for different values of [Formula: see text] and [Formula: see text ...

ANISOTROPIC BIANCHI-V PERFECT FLUID SPACE–TIME WITH VARIABLES G AND Λ
International Journal of Modern Physics A, 2010We study spatially homogeneous and anisotropic Bianchi-V perfect fluid cosmological model with variable G and Λ. Exact solutions to the field equations in the case of particle creation and in the absence of particle creation are obtained by assuming a constant deceleration parameter. The model has a big-bang-type singularity at the initial time t = 0.

Energy conditions for Bianchi type I universe in f(G) gravity
Astrophysics and Space Science, 2014In this paper, we discuss energy conditions in modified Gauss-Bonnet gravity for locally rotationally symmetric Bianchi type I universe model with perfect fluid. The matter contents are constructed to discuss the energy conditions bounds. We take two specific f(G) models along with present day values of Hubble, deceleration, jerk and snap parameters ...
