In the term of the project (three years) many results are obtained. Important results are shown as follows.
1. Uniqueness of the unbounded classical solution of the MHD system.
We obtain the uniqueness of the unbounded classical solution of the MHD system under suitable conditions on asymptotic behaviors, MHD system is the basis of the magnetic Benard problem which we have been studying in these years.
2. Mathematical and numerical analysis of Eguchi-Oki-Matsumura system.
We introduced the mathematical formulation of the EOM system and show the existence results. We made the numerical simulation of the one- dimmensional system and obtained the stability of the constant solutions.
3. Analysis of the third order equation.
We obtain the non-existence of the monotone solution of the third order equation arising in the phenomena of the liquid crysta, which has the close relation to Kuramoto-Shivashinsky equation.
4. Analysis of the complex system in the social science.
(a) We analyzed the reversibility of the Lindley process with discrete states.
(b) We determined the optimal inter-arrival times for the queuing system GI/GI/M/1.
5. Development of the fast numerical computation and its application.
We developed methods of fast numerical computations in the environment of the parallel computing offered by PVM. These methods enables the large-scaled numerical simulation of fluid mechanics.
6. We held the international symposiums and domestic symposiums, for example, Fourth Japan-Chine joint seminar on numerical mathematics, DDM12 and RIMS symposiums. We joined the several international symposiums and presented our results.
