摘要：

In this work, we study the cosmological implications of Kaniadakis holographic dark energy model in the context of Einstein and deformed Hotava-Lifshitz theories of gravity. We examine the various cosmological parameters to analyze the evolution of the universe. The Hubble parameter (H) is discussed as it is evidence for accelerating universe and source to examine some other cosmological parameters. We probe coincidence parameter ((r) over tilde) to check the matter- and energy-dominated eras of the universe. The deceleration parameter (g) is explored for the expansion behavior of the universe while the jerk parameter (j) is examined to compare the different dark energy models with ACDM (j = 1) model. We examine the equation of state parameter (omega(d)) to look into different phases of the universe. We calculate the perturbed parameter squared speed of sound (C-s(2)) 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.
