LRS Bianchi Type-I Cosmology with Gamma Law EoS in f(R, T) Gravity

We have studied the locally rotationally symmetric (LRS) Bianchi type-I line element in f(R, T) (R is the Ricci scalar and T is the trace of the stress energy tensor) theory of gravity in presence of EoS parameter. The simplest case of f (R, T) gravity, i.e. first choice, is considered. The "gamma-law" equations of state are considered to explore the role of particle creation in the early universe. The exact solutions of the field equations are obtained using the scalar expansion proportional to the shear. The physical and kinematical properties of the model are studied.
