Holographik, the k-essential approach to interactive models with
  modified holographic Ricci dark energy
  We make a scalar representation of interactive models with cold dark matter
and modified holographic Ricci dark energy through unified models driven by
scalar fields with non-canonical kinetic term. These models are applications of
the formalism of exotic k-essences generated by the global description of
cosmological models with two interactive fluids in the dark sector and in these
cases they correspond to usual k-essences. The formalism is applied to the
cases of constant potential in Friedmann-Robertson-Walker geometries.
