| Research Abstract |
We obtain exact black hole solutions in the theory with higher derivative terms and dilaton from superstrings, study their physical properties including global structure, and found the possibility that the singularity is weakened in such theories. We also give physical applications of the solutions. We also construct black hole solutions in renormalizable Horava gravity, and study their thermodynamic properties. We systematically construct time-dependent brane solutions and classify them, and also construct supersymmetric such solutions.
