Holographic dark energy with varying gravitational constant
arXiv:0906.2847 · doi:10.1016/j.physletb.2009.07.048
Abstract
We investigate the holographic dark energy scenario with a varying gravitational constant, in flat and non-flat background geometry. We extract the exact differential equations determining the evolution of the dark energy density-parameter, which include -variation correction terms. Performing a low-redshift expansion of the dark energy equation of state, we provide the involved parameters as functions of the current density parameters, of the holographic dark energy constant and of the -variation.
