Research Abstract |
We have investigated the cosmological solutions and the stabilization problem of the internal space on the basis of the higher-dimensional gravity theories. We have obtained the solutions which realize the accelerated universe with the finite volume of the internal space in the case of the positive scalar potential. We have showed that for the certain choice of parameters the universe settles down to accelerating expansion and the size of the internal space is fixed.
