Holographic connection of f(G) gravity through Barrow and a generalized version of holographic dark fluid

Abstract: In the context of f(G) modified gravity, we address the cosmic application of the most generalized form of holographic dark energy (The European Physical Journal C, 77, (2017): 1-8) in this study, as well as a specific instance of it in the form of Barrow holographic dark energy (Physical Review D, 102(12), p.123525). Holographic dark energy and a well-known power law form of the scale factor a(t) are added to the f(G) model in order to achieve this. It is observed that a sufficient criterion for a realistic modified gravity model is satisfied by the reconstructed f(G). The reconstruction models are also tested under the four energy situations.
