Research

Research Topics, Overview of the research

Research Topics
The topics I am interested in are as follows: (1) Numerical bifurcation analysis and Conley-Morse graphs, (2) A billiard problem in nonlinear and nonequilibrium systems, (3) Application of computer-assisted proofs via interval arithmetic.
Overview of the research
My research interest is understanding pattern formation phenomena from a viewpoint of bifurcation theory of dynamical systems. I am also interested in computer-assisted proofs based on interval arithmetic.

Research Areas

Natural sciences, Applied mathematics and statistics
