    • Abstract

       

      Here we have studied locally rotationally symmetric Bianchi-V Universe in the presence of modified theory for gravitation [$ f (R, T )$ theory] and for that, we considered a perfect fluid with heat conduction as the energy source. We used the law of variation for the deceleration parameter (DP) to solve field equations, as it gives a constant value of DP and is related to the average scale factor metric. Also, we have discussed the physical and geometrical properties of the model in detail.
