The generalized second law in irreversible thermodynamics for the interacting dark energy in a non-flat FRW universe enclosed by the apparent horizon

TL;DR

This paper examines whether the generalized second law of thermodynamics holds in a non-flat universe with interacting dark energy and cold dark matter, considering the apparent horizon as the boundary, and finds it is valid under certain conditions.

Contribution

It extends the analysis of the generalized second law to non-flat FRW universes with interacting dark energy within irreversible thermodynamics.

Findings

The law is satisfied for specific energy transfer constants.

The study applies to a universe enclosed by the apparent horizon.

Results support thermodynamic consistency in such cosmological models.

Abstract

We investigate the validity of the generalized second law in irreversible thermodynamics in a non-flat FRW universe containing the interacting dark energy with cold dark matter. The boundary of the universe is assumed to be enclosed by the dynamical apparent horizon. We show that for the present time, the generalized second law in nonequilibrium thermodynamics is satisfied for the special range of the energy transfer constants.
