Outline of Research at the Start

頂点作用素(超)代数のモジュラー不変性と,表現のテンソル積であるフュージョン積の関係について研究する.特に,モジュラー不変性を用いて表現圏のテンソル圏構造を記述するフェアリンデ型公式に着目し,この公式を非半単純な場合や,超代数の捩れ加群を含む圏に対して一般化することを目的とする研究を行う.更に,超代数の表現圏と偶部分の表現圏の類似性について考察を行う.

Outline of Final Research Achievements

In this project, we study modular invariance of vertex operator (super) algebras, tensor categories arising from vertex operator (super) algebras and modular linear differential equations.

In this resarch we find a new construction of modular forms used in the definition of one point functions on the torus for vertex operator superalgebras and a new description of modular Wronskians of vector-valued modular forms.

Academic Significance and Societal Importance of the Research Achievements

頂点作用素代数のモジュラー不変性は,数理物理学や整数論の観点からも興味深い対象である.本研究で得られた成果は,頂点作用素超代数の指標の理論やその指標の満たすモジュラー微分方程式の研究を行う際に有用であると考えられる.特に,頂点作用素超代数をモジュラー微分方程式を用いて分類する際には基本的な手法を与えるものであると期待される.
