Revealing some cosmological aspects of Kaniadakis entropy

TL;DR

This paper investigates how the truncated Kaniadakis entropy modifies Friedmann equations and explores its implications for cosmic acceleration and the role of its parameters as a cosmological constant.

Contribution

It introduces a cosmological model based on truncated Kaniadakis entropy and analyzes its effects on cosmic expansion and the parameter constraints.

Findings

K imposes constraints compatible with accelerated expansion

K can act as an effective cosmological constant

Modified Friedmann equations show significant cosmological implications

Abstract

Adopting the modifications induced by the truncated version of the Kaniadakis entropy on the Friedmann equations, we explore some relevant aspects of this cosmological scenario at the background level. We analyze the constraint imposed on the parameter $K$ obtained from the accelerated cosmic expansion condition, and we also study the role of such a parameter as a cosmological constant.
