Outline Activities

The main theme of my research is a combinatorial study of complex dynamical systems in dimension two, namely the complex Henon maps. I am now working on a criterion of their hyperbolicity, topology and combinatorics of their Julia sets and of their parameter loci, and applications of such complex methods to real dynamics.

I gave a series of lectures on the dynamics of complex Henon maps both in Tokyo Institute of Technology and in Hokkaido University, on symbolic dynamics and data storage in Tokushima University.

I gave a public lecture under the title "Dimension, Fractals and Dynamical Systems" organized by the Department of Mathematics, Kyushu University.
