The cosmology of an holographic induced gravity model with curvature
  effects
  We present an holographic model of the Dvali-Gabadadze-Porrati scenario with
a Gauss-Bonnet term in the bulk. We concentrate on the solution that
generalises the normal Dvali-Gabadadze-Porrati branch. It is well known that
this branch cannot describe the late-time acceleration of the universe even
with the inclusion of a Gauss-Bonnet term. Here, we show that this branch in
the presence of a Gauss-Bonnet curvature effect and an holographic dark energy
with the Hubble scale as the infra-red cutoff can describe the late-time
acceleration of the universe. It is worthwhile to stress that such an energy
density component cannot do the same job on the normal Dvali-Gabadadze-Porrati
branch (without Gauss-Bonnet modifications) nor in a standard 4-dimensional
relativistic model. The acceleration on the brane is also presented as being
induced through an effective dark energy which corresponds to a balance between
the holographic one and geometrical effects encoded through the Hubble
parameter.
