| Research Abstract |
We have investigated about stochastic systems and dynamic systems related to various fields of natural science and technology. We used mathematical tools from several fields, for instance, theory of probability, statistics, differential equation, functional analysis, geometry, numerical analysis and so on. We also applied our results to statistical physics and biological physics.
1. Stochastic System :
(1) Y. Fujikoshi : Asymptotic Expansions in Mathematical Statistics, Statistical Testing of the Growth Curve Model.
(2) H. Totoki : Hausdorff Dimension of Random Fractals, Cross Product of Random Dynamics.
2. Mathematical and Numerical Analysis of Dymanical Systems :
(1) M. Mimura etc : Stability and Bifurcations in Bistable Reaction Diffusion Systems.
(2) T. Kusano : Existence Theorem of Solutions for Monge-Ampere Equation.
(3) S. Oharu : Non-linear Perturbation of Semi-groups.
(4) F.-Y. Maeda : Martin Boundary of Harmonic Space.
3. Geometric Approach of Dynamic Systems :
(1) T. Matsumoto : Condition of Triviality for Knots of a Certain Kind.
(2) K. Okamoto : Kirillov-Kostant Theory and Feymnann's path integral. These results are closely related to applied mathematics, for example, mathematical physics and biophysics.
