Hence one can (1) give a coherent statistical interpretation of the wave function, and (2) define a Hilbert space of the states with all the usual quantum-mechanical formalism. A new linearized form of the wave equation, completely equivalent to the second-order one, is finally presented.

A specific representation shows that the Poisson brackets for canonical hydrodynamical observables become "averages" of quantum observables in the given state. Stochastic quantization thus justifies the standard procedure of replacing the classical particle (or field) observables with operators according to the scheme p,+ -ifia, and

This allows a canonical formulation that will be the first stage of the future Clebsch parametrization, i,e., a relativistic generalization of the 13ohm-Schiller-Tiomno pioneering work on the Pauli equation.

It is then shown that the nonlocal relativistic quantum potential approach plainly satisfies the Einstein causality criteria as well as the energy-momentum conservation in individual microprocesses. Furthermore, this approach bypasses a new causal paradox for timelike separated EPR measurements deduced by Sutherland in the frame of an approach by means of space-time zigzags with advanced potentials. It is finally demonstrated that this inherent quantum causal direct interaction establishes permanent EPR correlations which are always restricted to spacelike separations and are instantaneous only in the center-of-mass rest frame of the two-particle system.

The approach is investigated comparatively with the Bohm-Vigier model of stochastic fluctuations. Parallels to the causal interpretation of de Broglie-Bohm are drawn.

It is shown that the Bohr-tIcisenberg model yields testable predictions which differ from those of the Einstein-de Broglie theory of light.

The assumption of real physical paths in l' 4 implies that only particles {antiparticles) of positive energies move forward in time with positive probability densities.
