Abstract

We consider a connection between the holographic dark energy density and the kinetic k-essence energy density in a flat FRW universe. With the choice c = 1, the holographic dark energy can be described by a kinetic k-essence scalar field in a certain way. In this Letter we show this kinetic k-essential description of the holographic dark energy with c = 1 and reconstruct the kinetic k-essence function F (X). © 2009 Elsevier B.V. All rights reserved.
