Outline of Annual Research Achievements

結び目のKashaev不変量と双曲体積を関連づける体積予想は、量子トポロジーと双曲幾何を結びつける懸案の予想であり、最近15年間世界的にこの分野の中心的な話題となってきた。本研究の目標は、体積予想を多くの結び目について解決し、Kashaev不変量の漸近展開として得られるべき級数を新しい結び目不変量として研究することである。これにより、量子トポロジーと双曲幾何を融合する新しい研究テーマが創出されることが期待される。
また、3次元多様体の量子不変量の漸近展開に双曲体積が現れることを主張する「3次元多様体の体積予想」も近年定式化され、これについての研究もすすめた。とくに、漸近展開の準古典極限の項にはReidemeister torionが現れることが観察され、いくつかの例に対してそれを証明した。
また、国際会議「結び目理論の東アジアスクール」と、研究集会「Intelligence of Low-dimensional Topology」「結び目の数学」「トポロジーシンポジウム」「トポロジー新人セミナー」「Topology and Geometry of Low-dimensional Manifolds」「Fundamental Groups, Representations and Geometric Structures in 3-manifold Topology」を開催した。これらの国際会議と研究集会では、国内外の研究者による活発な研究交流が行われ、十分な成果を挙げた。
