THE MODELING OF SOME ASPECTS OF THE BEHAVIOR OF ECONOMIC SYSTEMS IN TWO-DIMENSIONAL SPACE

A. V. Ilman    
V. M. Ilman    

Resumen

For modeling economic systems with two conditions, it is offered to use the nonlinear variable dynamic model with two conventional conditions «demand» and «proposal». It is demonstrated that the points of balance, limiting cycles and relaxation variations of different order insist of such economic families.
