Abstract

We investigated the physical behavior of an LRS Bianchi type I cosmological model in the framework of the f(R,T) theory of gravity in the presence of a perfect fluid, where R is the Ricci scalar and T is the trace of the stress energy tensor of the matter. In order to obtain a deterministic solution of the field equations we assumed the special law of variation of the Hubble parameter proposed by Berman that yields the constant deceleration parameter. Some physical properties of the models are discussed.
