Shoman O. The Geometrical Modelling of General Parallel Sets

The dissertation is devoted to developing of the geometrical modelling theory of the general parallel sets for problems solving of geometrical objects form-formation in time which are visual geometrical models of dynamic phenomena and processes characterized by wave fronts surfaces which create the space conformal set in the moments of time with the lines on directions of these fronts moving or by isolines which are conformal to directions of physical parameters change. On introduced terminology basis the general approach to the geometrical modelling of different origin physical phenomena and processes displays is proposed. It was developed the theoretical basis of: the method of parallel sets geometrical models creation on the plane by means of Hamilton - Jacobi equation as eikonal equation for the curves with return and self-intersection points; the method of parallel sets geometrical models creation by means of normal equations for the surfaces in parameter form; the method based on conformal representations, in which the new geometrical meaning of twister complex potential function was proposed and the new geometrical models of quasi-parallel lines sets were obtained on the complex plane; the improved image extrapolation method for forecasting of geometrical form of lines on the plane as the elements of general parallel sets. These methods allow to research qualitative change of objects modelled.
