Abstract
In a nonperturbative theory for vector and scalar mesodynamics of the kind proposed by Salam, it is found that the ``gauge approximations'' introduced in this approach are the most sensible of a set of approximation schemes that preserve the scalar gauge properties of the amplitudes of the theory. The Green's functions used are those suggested by the functional derivative approach of the paper. The generalized identities of the Ward‐Takahashi kind that these Green's functions satisfy are exhibited, as well as the decomposition of the general n‐point function in terms of these Green's functions.
