Query: Holographic cosmology from "dimensional reduction" of ${\cal N}=4$ SYM
  vs. $AdS_5\times S^5$   We propose a way to obtain holographic cosmology models for 3+1 dimensional
cosmologies vs. 3 dimensional field theories from a "dimensional reduction"
procedure, obtained by integrating over the time direction, of (modifed)
standard holographic duals of 3+1 dimensional field theories. The example of a
modified ${\cal N}=4$ SYM vs. $AdS_5\times S^5$ is presented, and in
perturbation theory doesn't match observations, though at strong coupling it
might. But the proposed mechanism is more general, and it could in principle be
applied to other top down holographic models.
