Cosmographic and thermodynamic analysis of Kaniadakis holographic dark energy

In this work, we study the cosmological implications of Kaniadakis holographic dark energy model in the context of Einstein and deformed Hořava-Lifshitz theories of gravity. We examine the various cosmological parameters to analyze the evolution of the universe. The Hubble parameter [Formula: see text] is discussed as it is evidence for accelerating universe and source to examine some other cosmological parameters. We probe coincidence parameter [Formula: see text] to check the matter- and energy-dominated eras of the universe. The deceleration parameter [Formula: see text] is explored for the expansion behavior of the universe while the jerk parameter [Formula: see text] is examined to compare the different dark energy models with [Formula: see text]CDM [Formula: see text] model. We examine the equation of state parameter [Formula: see text] to look into different phases of the universe. We calculate the perturbed parameter squared speed of sound [Formula: see text] to assess the stable behavior of the model. We also investigate the behavior of rate of change of entropy to discuss the validity of generalized second law of thermodynamics.
