In my paper "Chubikalo and Smirnov-Rueda dualism: Foundation and
generalizations" i revised [Phys. Rev. E 1996: 53, 5373] and extended
dualism to gravitational case with next main conclusions:

Since this newsgroup is basically about classical results, I forgot to
say that Chubykalo and Smirnov-Rueda dualism is also extended to quantum
interactions.

In this way Quantum field theory is here recovered as special case of
limited applicability. E.g. the one-photon potential obtained from
Feynman QED is here derived after a number of approximations to a more
fundamental theory.

In the classical case, the approximations yield the concepts of geometry
and of retardation in interactions. The quantum case is specially
interesting because offers a foundation to why quantum field theory needs
to treat space in a *classical* way. As noticed by several authors QFT
breaks with the quantum mechanical treatment.

Moreover, in the quantum case the approximation does not introduce
retardation in the interaction. This is reason that distance in the field
theoretic potential energy between two electrons (e.g. the Gaunt
potential) is the distance at instant t instead at some retarded time t_0.


- No fundamental geometric formulation of interactions is possible. The
geometric formulation is recovered after a number of approximations.
Of course the geometric approximation works inside the field of
applicability.

- All main dual results in PRE are recovered and clarified. For example
the status of the hamiltonian action and radiation loses is clarified
and some minor mistakes corrected.

- The whole dual theory (\phi_0 + \phi^*) is founded in first order
mixed brackets of a Liouville space extension of mechanics.

- Particle interactions are *instantaneous*.
The retarded LW potentials for electromagnetism and gravity are
*recovered as approximation*. The approximation is valid when the
field description of interactions is valid. This explains why field
theoretic arguments give to the misguided claim that interactions are
retarded by c, which as was known in recent years is not true. See for
instance the PRE paper and several recent experimental works.
