Abstract:
In the paper the initial stages to obtain the dynamic equation of the relational
theory is discussed. As the limiting dynamic equation we use the equations
describing the relativistic dynamics of a three-dimensional spatial
hypersurface that is composed of a continuum set of arbitrary moving particles
and corresponding to the same value of their proper time. The relations
describing the internal geometry of the space hypersurface are obtained. The
problem of the interpretation of the spatial metrics of the dynamically evolving
space hypersurface in the case of a discrete set of particles is discussed.
