Coexistence of cosmological constant and holographic dark energy

Abstract:  In the scenario of multi-verse, it is much more natural that both the cosmological constant (CC) and the holographic dark energy (HDE) exist, for the former is a physical constant and thelatter is a finite size effect. We study this situation both theoretically and numerically, and find that indeed with the available observational data both CC and HDE exist.
