The interacting generalized Ricci dark energy model in non-flat universe
  We extend our previous analysis and consider the interacting holographic
Ricci dark energy (IRDE) model in non-flat universe. We study astrophysical
constraints on this model using the recent observations including the type Ia
supernovae (SNIa), the baryon acoustic oscillation (BAO), the cosmic microwave
background (CMB) anisotropy, and the Hubble parameter. It is shown that the
allowed parameter range for the fractional energy density of the curvature is
$-0.005$ $\lesssim$ $\Omega_{k0}$ $\lesssim$ $0.015$ in the presence of the
interactions between dark energy and matter. Without the interaction, the flat
universe is observationally disfavored in this model.
