In this paper, we have studied Friedmann-Robertson-Walker space-time in the presence of domain walls in the framework of f(G) theory of gravitation. We propose the generalization of linearly varying deceleration parameter. It is observed that the uni

In this paper, we study the model of f(T) gravity in the presence of dark matter and modified holographic Ricci dark energy (MHRDE) in locally rotationally symmetric (LRS) Bianchi type-I space–time. To achieve a physically realistic solution of the

In this work we have proposed a variable relation between densities of cosmic string. Bianchi type II,VIII and IX space time is explored in the context of general relativity. The field equations are solved by assuming that the shear scalar is proport

We study a hypersurface homogeneous space-time in the framework of the f (R, T) theory of gravitation in the presence of a perfect fluid. Exact solutions of field equations are obtained for exponential and power law volumetric expansions. We also sol
