What I am working on...
I am working on invariants of knots, links and 3-manifolds.
- Volume conjecture
We propose volume conjecture of knots with Hitoshi Murakami from Kashaev's conjecture, suggesting that the hyperbolic volume of the complement of a hyperbolic knot is determined by the Jones polynomial and its generalizations.
- Universal perturbative invariant
The universal perturbative invariant of 3-manifolds is constructed with T. T. Q. Le and T. Ohtsuki. I am studying on the representation of the mapping class groups constructed from the Topological Quantum Field Theory of the universal perturbative invariant.

- On web diagrams
Abstract: In this paper, web diagrams and web spaces are introduced and the construction of the universal perturbative invariant, taking values in the web space, is explained. Applying this invariant to the mapping cylinders of elements of the mapping class group Mg of the surface of genus g, we get web representations of Mg on the web space. The web space has two natural filtrations and these representations are compatible with these filtrations. This fact seems to explain that the representations are not so simple ones.
