چکیده

. In this paper, we evaluate the cosmological implications of dark energy from a holographic perspective in the framework of a modified Gauss-Bonnet theory of gravity f(G) with respect to the Granda-Oliveros cut-off. Therefore, using holographic dark energy (HDE) and two forms of the scale factor, we reconstruct the f(G) model and study the different conditions such as energy conditions (WEC), (DEC), and (SEC) and show whether it is satisfactory or not. Also, we discuss the dynamic analysis of these models regarding the important tools as statefinder diagnostic (r, s). Finally, we study the stability of the two models and compare the results with the latest observable data.
