Query: Holographic dark energy with varying gravitational constant in
  Horava-Lifshitz cosmology   We investigate the holographic dark energy scenario with a varying
gravitational constant in a flat background in the context of
Ho\v{r}ava-Lifshitz gravity. We extract the exact differential equation
determining the evolution of the dark energy density parameter, which includes
$G$ variation term. Also we discuss a cosmological implication of our work by
evaluating the dark energy equation of state for low redshifts containing
varying $G$ corrections.
