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

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.
