Integration of \(D\)-dimensional cosmological models with two factor spaces by reduction to the generalized Emden-Fowler equation
A general multidimensional cosmological model is developed which describes spaces with a mixture of several perfect fluid components as the source of the gravitational field. The equations of motion are integrable in some cases, in particular when there are two factor spaces and two fluid components. The Einstein equations then reduce to the Emden-Fowler equation. This method is then applied to specific new cosmological spaces.
