Application of this definition for symmetric analysis of theoretical physics equations is considered. The version of electrodynamics is constructed permitting the faster-than-light motions of particles with real masses. Some elements of physical interpretation of the proposed theory are presented.6 pages, LaTeX, Report at the 8th Word Multi-Conference on Systemics, Cybernetics and Informatics, July 18-21, 2004, Orlando, Florida, USA, http://www.iiisci.org/sci2004/General Physicstext
