N-Dimensional Bianchi Type-I Cosmological Model With Time Varying Deceleration Parameter in f(R,T) Theory

Abstract

In this paper, we have obtained exact solution of n-dimensional Bianchi type-I spacetime with perfect fluid distribution in the f(R, T) theory, for a special choice of f(R, T) = f₁(R) + f₂(T) with f₁(R) = λ₁R and f₂(T) = λ₂T . The solution of the corresponding field equations is obtained by assuming a periodically varying deceleration parameter. The physical and geometrical properties of the model have been discussed using some physical parameters.
