Research field 


Representation theory. 


Research of interest 


I am studying the representation theory and the integrable systems.In particular, the algebraic systems called quantum groups, which generalizes the notion of Lie groups as symmetries of equations, and the associated solvable systems such as integrable difference equations.

■ 
Advice on research 


The representation theory on Lie groups and Lie algebras and their quantum group version, spherical functions and Calogero type differential /difference operators and their generalizations associated with elliptic curves, and as the basis of these, soliton equations, solvable lattice model, and conformal field theory.

One word 

In this area, everyday life would be difficult because you must handle
many things in parallel. However, in the field I am studying, we can feel
such that “we have one mathematics”. For the quick introduction to this
field of study, we have a book, “Invitation to Mathematical Physics”,
by Hiroshi Ezawa (published by Yuseisha in 1994, in Japanese: Please read
chapters, 2, 3, 7 and 8, especially), or a book written by T Miwa, E Date,
M Jimbo "Solitons  differential equations, symmetries and infinite
dimensional algebras" (Cambridge university press, 2000).
