Title
Professor
Profile
My research area is dynamical system theory(the qualitative theory of ordinary differential equations) and ergodic theory. I study transfer operators associated to chaotic dynamical systems by using methods of functional analysis such as Fourier analysis and semi-classical analysis. My main target of research now is the geodesic flows on negatively curved manifold, which is a type of chaotic hyperbolic flow, and the corresponding transfer operators and semi-calsscial zeta funtions.
From April 2022, I have been working as the dean of Faculty of Mathematics, Graduate school of Mathematics and Joint Graduate school of Mathematics-for-Innovation.
For education, I gave a few lectures such as calculus, linear algebra, comlex function theory, dynamical system theory, etc) and supervised a few students in their studies of mathematics.

典型的なカオス的は流れ（連続力学系）であるアノソフ流における指数的混合性が生成的な条件の下で成立するかとうかは1970年代のアノソフやシナイの研究依頼の懸案であったが，その問題に対し3次元の場合に肯定的な解決を与えた． 結果と証明は論文 "Exponential mixing for generic volume-preserving Anosov flows in dimension three" (プレプリント， arXiv:1601.00063）で発表した．
