| Outline of Final Research Achievements |
Towards nonperturbative formulations of quantum theory including general relativity via quantization of open superstring field theory, we clarified that the structure of closed string perturbation theory which contains general relativity can be reproduced by the 1/N expansion of correlation functions of gauge-invariant operators in open bosonic string field theory. We also found a formula for correlation functions in quantum field theory using homotopy algebras, which can be powerful tools in quantizing open string field theory.

| Academic Significance and Societal Importance of the Research Achievements |
重力は一般相対性理論で記述され、ミクロな世界は量子力学で記述されるが、一般相対性理論と量子力学をひとつの理論的な枠組みの中で融合することには成功していない。本研究ではこの問題に対して開いた超弦の場の理論と呼ばれる理論を量子化することで解決の糸口を掴もうとするものであり、もう少し簡単な開いたボソニックな弦の場の理論では重要な進展があり、より難しい開いた超弦の場の理論を攻略するための武器の整備も順調に進めている。
