摘要
In this paper, we have studied the FRW metric for variable G and Lambda in f(R,T) gravity with the modified Chaplygin gas equation of state i.e. p = A rho - B/rho(n). We have used the hybrid exponential law (HEL) for scale factor to obtain the solution of the field equations. Here also we have discussed some physical behaviour of the model.
