Derivation of the relativistic 'proper-time' quantum evolution equations from canonical invariance

Based on (1) the spectral resolution of the energy operator; (2) the linearity of correspondence between physical observables and quantum self-adjoint operators; (3) the definition of conjugate coordinate–momentum variables in classical mechanics; and (4) the fact that the physical point in phase space remains unchanged under (canonical) transformations between one pair of conjugate variables to another, we are able to show that \bra{t_s}E_s\rangle , the proper-time rest-energy transformation matrices, are given as aexp(−iEsts/planck), from which we obtain the proper-time rest-energy evolution equation {\rm i}\hbar{\partial\over \partial t_s}\ket{\Psi}={\skew3\hat{E}_s}\ket{\Psi} . For special relativistic situations this equation can be reduced to the usual {\rm i}\hbar{\partial\over \partial t}\ket{\Psi}=\skew3\hat{E}\ket{\Psi} dynamical equations, where t is the 'reference time' and E is the total energy. Extension of these equations to accelerating frames is then provided.
