摘要

In this paper we have examined the Bianchi type-V model within the framework of linear model which is a special case of broader f (R, T) gravity framework proposed by Harko et al. Here we have considered the f (R, T) = R+ 2λT where λ is an arbitrary constant, R is the Ricci scalar, T is the trace of stress energy momentum tensor. To find the solution of field equations, we have assumed the condition that cosmic jerk parameter j is directly proportional to negative of deceleration parameter q, namely j ∝ – q. Different cases of Hubble parameter H, spacial volume V, deceleration parameter q, energy density ρ, pressure of matter p and cosmological constant Λ are discussed. Also, we have discussed the physical and geometrical properties of the model. Our results match with the observations.
