Mathematical Modelling the Ethnic System Victor Korobitsin and Julia Frolova Omsk State University, Computer Science Division, 55A, Mira pr., 644077 Omsk, Russia {korobits, frolova}@univer.omsk.su http://www.univer.omsk.su/socsys Abstract. The main of presented research is a demonstration of cre- ating the society model on ethnic solidarity level. This model describes the behavior of ethnic system. The ethnic system includes a few eth- noses and provides their interactions. The interactions transmit by eth- nic fields. The model is described by system of parabolic differential equations. The software TERRI is used for the forecast of arising the ethnic conflicts. Based on simulation result the researcher can compute the direction of ethnic field distribution and the most probable points of skirmish between ethnoses. 1 Introduction The modelling of biosphere (ecological) processes gave rise to the research of society development. These models were destined for solving the problem of global change the ecological situation. Now the problem of interethnic conflicts is growing in society. It forces the international organizations to find the way for its adjustment. The modelling of global ethnic processes will allows to evaluate the world ethnic situation. The aim of this research is the construction of mathematical model of ethnic field. The model is described by the system of parabolic equations. It is the tools for research the evolution of interactive ethnic systems under landscape influence. 2 Ethnic Solidarity Level On the ethnosphere level the traditions play the special role in the society. The people get the behavior stereotypes from them. Thereby the general function of this level is the sample maintenance. The individuals strive for conservation of culture as a collection of history experience. The ethnos is a people group, formed on basis of the original behavior stereo- type. It exists as a energy system, opposing itself to other like groups. Thereby people are divided on own and alien man. The main ethnos attribute is a be- havior stereotype. It is a complex of behavior standards of ethnos members. The collection of behavior stereotypes is defined by ethnic tradition differed the ethnos from biological population. P.M.A. Sloot et al.
