摘要：

In this paper, we investigate Friedmann-Robert-son-Walker (FRW) cosmological model in the presence of perfect fluid source in f (R, T) gravity. We have used linearly varying deceleration parameter proposed by Akarsu and Dereli (Int. J. Theor. Phys. 51:612, 2012) and barotropic equation of state to obtain determinate solution of the field equations of the theory. Physical parameters of the model are determined and some physical and kinematical properties of the model are also discussed. Keywords f (R, T) gravity
