PHYSICAL EQUIVALENCE OF THREE FORMS OF RELATIVISTIC DYNAMICS AND ADDITION OF INTERACTIONS IN THE FRONT AND INSTANT FORMS

摘要

The point, instant and front form of relativistic Hamiltonian theory are shown to be S-matrix equivalent in the general case(of many channels and particles with spin) .The cor¬responding transformations are explicitly found. The problem of relativistic addition of the direct interactions is solved for the front and instant forms of dynamics.
