Outline of Research at the Start

Borel総和法により、微分方程式のWKB解と呼ばれる形式解に意味づけを与えて解析する手法が完全WKB解析である。完全WKB解析は微分方程式の解の大域解析に有効である。完全WKB解析に行列模型の研究手法である位相的漸化式の視点を導入し、多変数超幾何系の解析を行うことで、偏微分方程式系の理論整備を目指す。

Outline of Final Research Achievements

We constructed a relation between Voros coefficients in the exact WKB analysis and the free energy in the topological recursion, based on the theory of quantum curves. In this research we mainly studied the hypergeometric differential equations with 2 variables, and obtained the quantization, the relation between Voros coefficients and the free energy, and the explicit forms of Voros coefficients and the free energy.

Academic Significance and Societal Importance of the Research Achievements

本研究は背景の全く異なる完全WKB解析と位相的漸化式の間の新たな関係性を与えるものである。また、線形常微分方程式と比較して、多変数の偏微分方程式系に対する漸近解析は発展途上である。本研究で得られた成果は、多変数の偏微分方程式系に対する完全WKB解析の発展に向けての一歩となることも期待される。
