A spacelike-surface state functional and local-deformation formalism exposes Lorentz-compatible free/interaction separation under explicit commutation/density conditions.
Scientific scope
A spacelike-surface state functional and local-deformation formalism exposes Lorentz-compatible free/interaction separation under explicit commutation/density conditions. Exact contribution is the 1943 formulation as represented by its 1946 English translation; Japanese original unread and no separate translation achievement. The argument assumes a scalar interaction-energy density and the required commutation at separated and adjacent spacelike points, motivated by the stated derivative-free interaction setting. Fields are transformed with free evolution; the surface-state equations are formal and restricted to spacelike surfaces, not arbitrary timelike boundaries. Section 4 handles continuum amplitudes through an indicated countable approximation and states results rather than supplying a modern measure-theoretic construction. Section 6 explicitly retains divergence problems and says the equations have pathological infinite solutions; this is not a renormalization proof, rigorous existence theorem for interacting continuum QFT or new verified physical prediction. equation images/glyphs imperfect, no independent reconstruction, replay or original-Japanese verification. Dirac/Bloch, Pauli, Stueckelberg, Heisenberg and Yukawa inputs remain inherited. Later Schwinger formulations, QED corrections and experimental confirmations are separate.
