摘要
Motivated by the work of Karami and Fehri (Phys. Lett. B, 684, 61 (2010)). We generalize their work with varying G. We investigate the new holographic dark energy model with varying G. We consider a spatially nonflat universe containing interacting new holographic dark energy with pressureless dark matter. We obtain the equation of state and the deceleration parameters. Also we reconstruct omega(A) for a = a(0)t(n) and H = [alpha/(alpha - 1)](1/t) in the late time universe. We also obtain q for a = a0tn and H = [beta/(alpha - 1)](1/t) in the present time universe, which describes accelerated expansion of the universe.
