Description
An anisotropic Bianchi type-III universe is investigated in presence of perfect fluid within the framework of f(R; T) gravity where R is the Ricci scalar and T is the trace of the energy momentum tensor, for the choice of functional f(R; T) = R + 2f(T) and f(R; T) = f1(R) + f2(T). We have shown that the field equations are solvable for any arbitrary function of a scale factor. To get a physically realistic model of the universe, we have assumed a simple power-law form of a scale factor. The exact solutions of the field equations are obtained which represent an expanding model of the universe starts expanding with a big bang at t = 0. The physical behaviours of the models are discussed
