Outline of Final Research Achievements

We examine superstring theory and quantum gravity by making use of higher spin symmetry appearing at the high energy limit of superstring theory. In particular, we use gauge/gravity correspondence, which enables us to analyze quantum gravity in terms of well-formulated conformal field theory. In this research project, we developed new methods to deal with conformal field theory. Applying the method, we derived gauge/gravity correspondence involving the high energy limit of strings. Furthermore, we proposed, verified, and applied the gauge/gravity correspondence using higher spin gravity in expanding universe.

Academic Significance and Societal Importance of the Research Achievements

宇宙がどのように始まったかは、世界の根源とも言える問いである。まだ簡単化した模型の段階ではあるが、私たちの研究結果により定量的に取り組めるようになった。より現実的な宇宙への拡張が今後の課題である。また、共形場理論やゲージ重力対応は応用範囲が非常に広く、私たちの研究結果はこれらの基礎的な性質の理解にも役立つと考えている。
