  This paper suggests that traditional fermi-bose quantum field theories (QFT)
in 3+1-D, like the standard model of physics, may often be exactly equivalent
to the limiting case of a family of bosonic QFT (BQFT) which generate soliton
solutions and are "finite." They are "finite" in the sense of being
well-defined mathematically even without regularization or renormalization,
though the coupling coefficients would of course be so large that we must use
nonperturbative methods for the analysis. Proof of this would open the door to
a completely finite, well-defined unification of physics without a need to
postulate additional unobserved dimensions of space-time. Axiomatic existence
of the BQFT is discussed. Possible relevance to empirical QCD is noted briefly
at the end.
