The requirement of gauge invariance for the Stückelberg equation for the relativistically covariant wave function of a system evolving according a universal world (or historical) time T implies the existence of a five dimensional pre-Maxwell field on the manifold of spacetime and r. The Maxwell theory is contained in this theory; integration of the field equations over r restores the Maxwell equations...
The scattering theory of Lax and Phillips, designed primarily for hyperbolic systems, such as electromagnetic or acoustic waves, is described. The embedding of the quantum theory into this structure, carried out by Flesia and Piron, is reviewed. We show how the density matrix for an effectively pure state can evolve to an effectively mixed state (decoherence) in this framework. Necessary conditions...
