| Research Abstract |
The investigations of high-energy particle physics and the evolution of the Universe strongly suggest that our Universe has dimensions greater than 4 on super-micro scales. In order to make clear the validity of this suggestion, we have studied the behavior and properties of universe models and black holes in higher-dimensional gravity theories. As an achievement, we have found a candidate solution describing a dynamical process for a four-dimensional spacetime to be obtained from a higher-dimensional spacetime. Further, we have examined the stability of black holes in higher-dimensional Einstein gravity systematically, and among all, we have discovered that a rapidly rotating black hole is dynamically unstable in higher-dimensional spacetime with negative cosmological constant.
