Multidimensional gravitational model with anisotropic pressure

Understand

We consider the gravitational model with additional spatial dimensions and anisotropic pressure which is nonzero only in these dimensions.

• Cosmological solutions in this model include accelerated expansion of the Universe at late age of its evolution and dynamical compactification of extra dimensions.
• This model describes observational data for Type Ia supernovae on the level or better than the $\Lambda$CDM model.
• We analyze two equations of state resulting in different predictions for further evolution, but in both variants the acceleration epoch is finite.
