Slow-roll inflation in (dual) Kaniadakis cosmology
The authors derive modified Friedmann equations from Kaniadakis entropy, compute inflationary observables, and find that Planck data require the deformation parameter kappa to be strongly suppressed in the standard case while allowing limited viable regions in the dual formulation.
