Numerical Study of Nonlinear Dynamics of a Population System with Time Delay

Autor: Dushkov, Ivan N., Jordanov, Ivan, Vitanov, Nikolay K.

Mathematical models of interacting populations are often constructed as systems of differential equations, which describe how populations change with time. Below we study one such model connected to the nonlinear dynamics of a system of populations i

On nonlinear waves of the blood flow through arteries

Autor: Nikolova, Elena, Jordanov, Ivan P., Vitanov, Nikolay K.

We discuss propagation of traveling waves in a blood filled elastic artery with an axially symmetric dilatation (an idealized aneurysm). The processes in the injured artery are modelled by equations for the motion of the wall of the artery and by equ

On Nonlinear Waves in the Spatio-Temporal Dynamics of Interacting Populations

Autor: jordanov, Ivan, Vitanov, Nikolay K., Nikolova, Elena

In this paper the spatial-temporal dynamics of the members of interacting populations is described by nonlinear partial differential equations. We consider the migration as a diffusion process influenced by the changing values of the birth rates and

Analysis of a Japan government intervention on the domestic agriculture market

Autor: Vitanov, Nikolay K., Sakai, Kenshi, Jordanov, Ivan P., Managi, Shunsuke, Demura, Katsuhiko

We investigate an economic system in which one large agent - the Japan government changes the environment of numerous smaller agents - the Japan agriculture producers by indirect regulation of prices of agriculture goods. The reason for this interven
