Outline of Final Research Achievements

The volume conjecture relates the Kashaev invariant of knots and the hyperbolic volume, and it is an important conjecture which relates the quantum topology and the hyperbolic geometry. I showed that the volume conjecture holds for hyperbolic knots with up to 7 crossings. Further, "the volume conjecture for 3-manifolds" is proposed recently, and I showed that this conjecture holds for hyperbolic 3-manifolds obtained by integral surgery along the figure-eight knot.
Further, we hold the international conference "East Asian Conference on Geometric Topology" and the conferences "Intelligence of Low-dimensional Topology", "Mathematical Sciences of Knot" and "Topology Symposium".

Academic Significance and Societal Importance of the Research Achievements

幾何化定理により、3次元多様体の分類問題は、3次元双曲多様体の分類に帰着される。さらに、3次元双曲多様体の分類は、リー群PSL(2,C)のある種の離散部分群の分類に帰着されるが、しかし、その分類を実際に実行するのは困難である。
一方、量子トポロジーにおいて、最強の量子不変量であるLMO不変量がホモロジー球面を分類することが期待されている。体積予想を手がかりにして、双曲幾何と量子トポロジーを融合させることが、3次元多様体の分類問題の観点からも重要であるとおもわれる。
