Abstract:

In this study, we investigated the Bianchi type-V model in the context of f(R, T) gravity.

Here, we have considered the f(R, T)=R+2f(T), where f(T)= λT where λ is an arbitrary constant, R is the Ricci scalar, and T is the trace of stress energy momentum tensor. We have made the assumption that the cosmic jerk parameter, j, is precisely proportional to the negative of the deceleration parameter, q, namely in order to solve the field equations. The conversation covers a variety of situations including the Hubble parameter (H), the spatial volume (V), the deceleration parameter (q), the energy density (ρ), the pressure of matter (p), and the cosmological constant (Λ). We investigate a bouncing point, the moment of transition between contraction to expansion. The value of the expansion scalar θ describes a smooth, bounded transition between contraction and expansion which represents a bouncing universe (avoiding Big Bang singularity) and also represents a bouncing universe with maximum expansion rate due to modified gravity. The model also diagnoses the de Sitter universe, where exponential expansion is driven by a cosmological constant or dark energy. The model looks at the physical and geometrical behavior of the model, as well as the exact solutions under the anticipated jerk parameter condition, and summarizes key findings.
