- Abstract
We investigate Kaniadakis holographic dark energy (KHDE) model taking the apparent horizon as the IR cutoff in a flat Friedmann-Lemaître-Robertson-Walker (FLRW) universe. We apply variant dark energy (DE) diagnostic tool to study KHDE model in flat universe with different values of the constant C 2 and Kaniadakis entropy parameter k. We use the tools statefinder hierarchy (S 3 (1) , S 3 (2) , S 4 (1) , S 4 (2)) , fractional growth parameter and composite null diagnostic (CND), which is blend of (S 3 (1) , (S 4 (1)) and . The evolution of trajectories of S 3 (1) , S 3 (2) , S 4 (1) and S 4 (2) depicts that there occur degeneracies in early time and also in the far future, whereas, in between these two extremes they are discriminated distinctly. The analysis of the present work shows that by the inclusion of fractional growth parameter with statefinder hierarchy (CND) degeneracy is removed reasonably, particularly more in the low redshift region.
