Abstract:

IF THE GROUP PROPERTY macroscopic causality of the U-matrix S-matrix computed between finite initial and final times is postulated, the proof of its unitarity reduces to a most simple verification on the propagation kernels of the theory. The Appendix gives an explicit proof of that property for electro- and meso-dynamics by means of perturbative expansions, which may be easily generalized. Author
