Abstract

We present a dilatonic description of the holographic dark energy by connecting the holographic dark energy density with the dilaton scalar field energy density in a flat Friedmann-Robertson-Walker universe. We show that this model can describe the observed accelerated expansion of our universe with the choice c1c\geq1 and reconstruct the kinetic term as well as the dynamics of the dilaton scalar field.
