| Outline of Final Research Achievements |
Four-dimensional N=2 superconformal field theories called the Argyres-Douglas theories are non-local theories, where we cannot apply standard method of field theories. In this study, we focus on the quantum Seiberg-Witten periods which characterize the low-energy effective theories and studied them using the exact WKB analysis and the ODE/IM correspondence. I determined the quantum Seiberg-WItten periods for the Schroedinger-type differential equations with a polynomial potential by the thermodynamic Bethe ansatz(TBA) equations. By generalizing the ODE/IM correspondence to the higher-order ODE, we also confirm the relation between the quantum Seiberg-Witten periods and the TBA equations.

| Academic Significance and Societal Importance of the Research Achievements |
摂動論など従来の手法で解析が困難と見られてきた強結合領域における場の量子論を, 2次元の量子可積分模型や常微分方程式の解の接続問題と共通な数学的構造があることを見出すことにより研究する新しい手法を開発した。またこの手法は量子力学のスペクトル問題を量子可積分的手法により厳密に解く新しい手法を与えるなど、摂動論を越えた物理の理解に大きく貢献するものである。
