Dark Matter and Cosmic Phenomena

At the present paper, Locally Rotationally Symmetric (LRS) Bianchi type-II cosmological model with interacting dark matter (DM) and holographic dark energy (DE) have been discussed.In order to obtain solutions of the field equations, it is assume that the shear scalar ( σ ) is proportional to expansion scalar ( θ ).To have a general description of holographic dark energy and dark matter, a phenomenological parameterization of dark energy in terms of its equation of state (EoS) has been taken.Statefinder diagnostic pair i.e. { } , r s is adopted to separate other existing dark energy models from this model.Here we discuss two models: when 1 2 n = , we obtain acyclic universe and the model converges into phantom region whereas when 3 2 n =, we get a expanding universe and the model converges into quintessence region.Some important geometrical and physical features regarding to this model have also been studied.
