| Outline of Final Research Achievements |
The principal research subject is the mathematical relation of models with nonlinear difference equations and nonlinear differential equations for the theoretical study about the biological popoulation dynamics. In this research project, to be systematically discussed is the rationality of the mathematical structure in such models, that is, its logical relation to the biological structure of targeted phenomenon. It is aimed to provide with a mathematical base to promote some new mathematical modeling, and to analyze the mathematical model newly built by it. Especially for some typical mathematical models in mathematical ecology, this project focused the formulus of functions involved in them and revisited the modeling to find out some new raltionality in them. As a result, some new mathematical models in biological population dynamics were built with the system of difference equations, and considered their mathematical natures.
