| Research Abstract |
[1] Study on nonlinear difference equations
Analytic solutions, their existency and asymptotic representations, are investigated for nonlinear difference equations of the first order or higher order. We wish to determine the structure of solution manifolds for these equations.
[2] Study on nonlinear partial differential equations
3-dimensional stationary Stokes equations are investigated when the boundary conditions of the first kind and of the second kind are given simultaneously. Free boundary problem in a shaft furnace is investigated with penalty method, and further treated numerically. 2-dimensional equilibrium plasma with symmetric cross section is investigated, both theoretically and numerically. Nonlinear evolution equations of Moser's type are investigated with the general Newton method. Cauchy problems for quasi-linear wave equations are investigated. Existency of global solutions will be further investigated.
[3] Study on system theory
Linear dynamical systems with infinite dimensional state spaces are investigated. The necessary and sufficient conditions for the existence of fine moduli spaces are obtained.
