Perfect fluid and heat flow in f(R,T) theory

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. (author)
