Abstract

Bianchi Type V Anisotropic Cosmological Model with a Dynamic Cosmological Constant Λ(<em>t</em>) along with Quadratic Deceleration Parameter in <em>f</em>(R, T) Gravity

“…In this model, adding time dependent cosmological constant Λ(t) in field equations cause a change in pressure and energy density formula as shown in [26,27]. We notice that for three types of n cosmological constant, pressure and energy density show same graphical presentation.…”

“…For this model, we now explain some geometrical and mathematical insights of cosmological parameters, differentiating eq. (25) and (26) with respect to time (t). Where, the axis-dependent Hubble parameter is…”

Role of Relativistic Charged Perfect Fluid in Bianchi type-III Space-time in Brans-Dicke theory of gravitation

“…In Brans-Dicke theory of gravity, Bianchi type-III cosmological model with a negative constant deceleration parameter in presence of perfect fluid have been studied by Adhav et al [8], Katore et al [9] explored a plane symmetric space-time filled with dark energy models in Brans-Dicke theory, Bhoyar et al [10] studied Bianchi type-III and Kantowski Sachs cosmological model containing a magnetic field with variable cosmological constant. Lorenz-Petzold [11], Kumar et al [12], Pawar et al [13], Rao et al [14], Naidu et al [15], Kandalkar et al [16],Mete et al [17],Sireesha et al [18],Hegazy et al [19],Trivedi et al [20] are some of the authors who have investigated several aspects of Brans-Dicke theory of gravitation. In the presence of the magnetic field, Tikekar and Patel [21] have acquired some exact Bianchi type-III cosmological solutions of massive string.…”

To Study the Bianchi type V Cosmological Model with Quadratic Equation of State in Modified theory of Gravity

“…Ramesh et al investigated Cosmological models with linearly varying deceleration parameter in ݂(ܴ, ܶ) gravity using Friedmann-Robertson-Walker (FRW) cosmological model in the presence of perfect fluid source [17]. Adhav examined Bianchi type-I cosmological model in general relativity which gives output about the earlier phase of time deceleration and present phase of time acceleration [18]. Kandalkar et al investigated Linear Equation of State with Brans-Dicke Theory of Gravitation using Bianchi type-V model [19].…”
