Abstract
For nucleons and pions, the relations between the propagators and vertex functions that describe the vector electroweak transitions have been derived directly as a natural consequence of the symmetries of the strong and electroweak interactions of hadrons. Significantly, the system under study includes various strongly interacting hadrons. The electromagnetic corrections to the vertex functions and propagators of the hadrons are taken into account to within e 2. The results obtained are discussed in connection with the calculation of radiative corrections in the description of electroweak transitions of nucleons and pions.
