Crossing the phantom divide line in the Holographic dark energy model in a closed universe

TL;DR

This paper investigates the conditions under which holographic dark energy models in a closed universe can cross the phantom divide line, exploring implications for the coincidence problem.

Contribution

It identifies specific conditions for crossing the phantom divide in holographic dark energy within a closed universe, linking it to the coincidence problem.

Findings

Conditions for crossing the phantom divide are established.

Relationship between crossing and the coincidence problem is analyzed.

Implications for cosmological models are discussed.

Abstract

Conditions needed to cross the phantom divide line in an interacting holographic dark energy model in closed Friedmann- Robertson-Walker universe are discussed. The probable relationship between this crossing and the coincidence problem is studied.
