| Research Abstract |
We can obtain exact solutions of Kaluza-Klein black holes with a twisted extra dimension which are asymptotically locally flat in five dimensions. In this type of black holes, we have constructed charged, rotating black holes, and extremal charged multi-black holes. We have investigated physical properties of Kaluza-Klein black holes : topology of horizons, analyticity of horizons, stability of solutions, thermodynamics of black holes, coalescence of black holes, motions of test objects around black holes.
