Abstract

In this paper, we discuss cosmological application of holographic Dark Energy (HDE) in the framework of f(G)f(G) modified gravity. For this purpose, we construct f(G)f(G) model with the inclusion of HDE and a well-known power law form of the scale factor a(t)a(t). The reconstructed f(G)f(G) is found to satisfy a sufficient condition for a realistic modified gravity model. We find quintessence behavior of effective equation of state (EoS) parameter ωDE\omega_{DE} through energy conditions in this context. Also, we observe that the squared speed of sound vs2v_s^2 remains negative which shows the instability of HDE f(G)f(G) model.
