Validity of the Generalized Second Law of Thermodynamics of the Universe Bounded by the Event Horizon in Brane Scenario

TL;DR

This paper investigates whether the generalized second law of thermodynamics holds for the universe bounded by the event horizon within brane-world gravity, considering both perfect fluid and holographic dark energy models.

Contribution

It analyzes the validity of GSLT in brane-world scenarios with different cosmic models, providing insights into thermodynamic laws in modified gravity.

Findings

GSLT holds under certain conditions in brane-world models.

Validity depends on the type of cosmic fluid and energy model.

Provides criteria for thermodynamic law applicability in brane cosmology.

Abstract

In this paper, we examine the validity of the generalized second law of thermodynamics (GSLT) of the universe bounded by the event horizon in brane-world gravity. Here we consider homogeneous and isotropic model of the universe filled with perfect fluid in one case and in another case holographic dark energy model of the universe has been considered. The conclusions are presented point wise.
