Abstract

We study the model for holographic dark energy in a spatially closed universe, generalizing the proposal in hep-th/0403127 for a flat universe. We provide independent arguments for the choice of the parameter in the holographic dark energy model. On the one hand, can not be less than 1, to avoid violating the second law of thermodynamics. On the other hand, observation suggests be very close to 1, it is hard to justify a small deviation of from 1, if .
