摘要：
In this Letter we have studied a closed universe which a holographic energy on the brane whose energy density is described by rho(H) = 3c(2)H(2) and we obtain an equation for the Hubble parameter. This equation gave us different physical behavior depending if c(2) > 1 or c(2) < 1 against of the sign of the brane tension. (C) 2008 Elsevier B.V. All rights reserved.
