Abstract :
The interaction of dark energy in the LRS Bianchi type-I line element is explored on the background
of f(R, T) gravity, where R and T denotes the Ricci scalar together with the trace of energy
momentum tensor of matter respectively. Here modified field equations are calculated using
f(R, T) = f1(R) + f2(T) together with inhomogeneous equation of state (EoS), p = ωρ − Λ(t),
where ω is constant. The solutions of modified Einstein field equations (EFE) obtained are solved by
taking a periodic time varying deceleration parameter (DP). Our model shows periodic nature with
Big-Bang prevailing at time t = 0. An investigation is done on the energy conditions and found that
the conditions of null energy and strong energy are found to be violated. We analyse the geometrical
and physical behaviours of these models.
