Taking R as generating function, the potentials of the electromagnetic and weak interactions are obtained by applying the causal d'Alembertian operator on R, and both potentials can be given a proper physical interpretation provided all calculations are made in the context of nonlinear generalized functions.12 pagesMathematical Physicstext
