Abstract(in English) | Mathematical modeling of nonlinear phenomena is effective in understanding their principles, and many mathematical models of organic phenomena with systems of reaction-diffusion equations have particularly presented [2]-[4]. In this paper, we propose a population dynamics model to which the diffusion coefficient for the diffusive motion and chemotaxis in the model of Escherichia coli [2] is applied, and show that the model can represent such phenomena peculiar to population dynamics such as depopulation, overpopulation and hollowing-out effect. Applying the proposed model to the two-sex population dynamics model [5], [6], we also show a case study of population dynamics based on the extended two-sex mode by numerical simulation. |
