Role of <i>f</i>(<i>R,T</i>) Gravity in Bianchi Type-V Dark Energy Model with Electromagnetic Field based on Lyra Geometry

Abstract

In this paper, a Bianchi type V Dark energy cosmological model scenario is studied with the electromagnetic field in Lyra based on f(R,T) gravity. The source of the magnetic field is along the x axis. Field equations found in Lyra geometry with electromagnetic field (F23 ≠ 0) in f(R,T) gravity, by choosing f(R~,T) = f1(R~) + f2(T) with f1(R~) + μR~ and f2(T) = μT. A hybrid scale factor discusses the physical and dynamical aspects of f(R,T) gravity.

Five-Dimensional Cosmological Model with One Dimensional Cosmic String Coupled with Zero Mass Scalar Field in Lyra Manifold

“…Our aim is to derive the exact solutions of the field equations by assuming the following two extra conditions: i) The special law of variation for the Hubble parameter proposed by Berman [28], which yields a constant deceleration parameter defined by ̈ ̇ = Constant (25) ii) Assuming that the shear scalar is proportional to scalar expansion proposed by Collins [29], which leads to a condition (26) where is constant, and it takes care of the anisotropic nature of the model. Solving equation ( 25) yields to , (27) where and are constants of integration. This equation point towards the condition for the accelerated expansion of the universe is .…”

“…Basumatary et al [26] have explored the Bianchi type VI 0 dark energy model with a particular form of scale factor in Sen-Dunn's theory of gravitation. Brahma et al [27] have reviewed Bianchi type-V dark energy cosmological model with the electromagnetic field in Lyra based on gravity. Inspired by the above discussions, in this paper, a higher dimensional bulk viscous fluid cosmological model with one-dimensional cosmic string is studied in the presence of interacting zero mass scalar field in Lyra geometry with the aid of Bianchi type-III spacetime.…”

“…Johri and Sudharsan have studied bulk viscous cosmological models in the Brans-Dicke theory of gravitation [30]. Several researchers [31][32][33][34][35][36][37] have recently explored the Bianchi type and Kaluza-Klein bulk viscous string cosmological models in the Saez-Ballester theory and the f (R, T) modified theory of gravity.…”
