| Outline of Final Research Achievements |
Exotic branes are important ingredients of string theory whose significance has long been unappreciated. In the present research, we studied basic properties of exotic branes, and clarified how to define their charges and how to classify them. Exotic branes are expected to play an important role in black hole microphysics, because black hole microstates may be represented by superstrata which generically include exotic branes. In this research, we constructed simple superstrata in the framework of supergravity, and showed that they are parametrized by arbitrary surfaces, leading to large entropy.
