Kaniadakis holographic dark energy: observational constraints and global
  dynamics
  We investigate Kaniadakis-holographic dark energy by confronting it with
observations. We perform a Markov Chain Monte Carlo analysis using cosmic
chronometers, supernovae type Ia, and Baryon Acoustic Oscillations data.
Concerning the Kaniadakis parameter, we find that it is constrained around
zero, namely around the value in which Kaniadakis entropy recovers standard
Bekenstein-Hawking one. Additionally, for the present matter density parameter
$\Omega_m^{(0)}$, we obtain a value slightly smaller compared to $\Lambda$CDM
scenario. Furthermore, we reconstruct the evolution of the Hubble, deceleration
and jerk parameters extracting the deceleration-acceleration transition
redshift as $z_T = 0.86^{+0.21}_{-0.14}$. Finally, performing a detailed local
and global dynamical system analysis, we find that the past attractor of the
Universe is the matter-dominated solution, while the late-time stable solution
is the dark-energy-dominated one.
