| Outline of Final Research Achievements |
Black hole entropy, which is given by the surface area, has two aspects: thermodynamic entropy and Noether charge. This research aims to clarify the relation of the two characterizations, which should lead to understanding of the origin of holography and information problem. We have constructed a self-consistent solution of evaporating black holes under assumption of spherical symmetry. In the solution, integrating entropy density of matter inside the hole reproduces the area law of black hole entropy. We have also formulated thermodynamic entropy as a Noether invariant in quantum mechanical systems. In future, these results should build a bridge between the two aspects of black hole entropy.
