| Abstract: | We consider cosmological evolutions in the 8-dimensional Einstein-Yang-Mills theory. The total spacetime consists of a 4-dimensional universe and 4-extra dimensions. An instanton in the extra dimensions generates an accelerating universe together with dynamical compactification. Then, we consider matters to this spacetime. These matters generate various cosmological evolutions, such as de Sitter and bounce universes. In addition, we discuss the null-energy condition and Maldacena-Nunez no-go t |
