“…Bianchi type models are among the simplest models with anisotropic background. Many authors [59][60][61][62][63][64] investigated Bianchi type spacetimes in different contexts. Kumar and Singh [65] solved the field equations in the presence of a perfect fluid using a Bianchi type I spacetime in general relativity (GR).…”

This manuscript is devoted to the investigation of the Bianchi type I universe in the context of f (R, T ) gravity. For this purpose, we explore the exact solutions of locally rotationally symmetric Bianchi type I spacetime. The modified field equations are solved by assuming an expansion scalar θ proportional to the shear scalar σ , which gives A = B n , where A, B are the metric coefficients and n is an arbitrary constant. In particular, three solutions have been found and physical quantities are calculated in each case.

The main purpose of this paper is to explore the solutions of Bianchi type III cosmological model in Brans Dicke theory of gravity in the background of anisotropic dark energy. We use the assumption of constant deceleration parameter and power law relation between scalar field φ and scale factor a to find the solutions. The physical behavior of the solutions has been discussed using some physical quantities.

“…Johri et al [9] investigated the general Bianchi type I cosmological solution corresponding to spatially homogeneous and anisotropic models containing barotropic fluid.Cosmological models with heat flow have been studied by various author viz. Novello and Reboucas [10], Ray [11], Reboucas and Lima [12], Roy and Banerjee [13,14].Bagora [15][16] fluid distribution. Motivated by these studies, in this paper we propose to find tilted Bianchi type I cosmological model for barotropic fluid.Also, we assumed that the expansion in the model is only in two directions i.e.…”
