【 摘 要 】

We consider a Chern-Simons gravity theory in the cosmological context for a flat Friedmann-Robertson-Walker metric in five dimensions, chosen barotropic perfect fluids filled the Universe, that is, an equation of state with constant state parameter for the fluid representing the h field of Einstein-Chern-Simons cosmology and an equation of state with variable state parameter for the fluid representing the matter field.
