It is shown that in a class of models of quantum field theory, the perturbation expansion of the resolvent operator, (H - z)-1, converges for all complex z. The class of models eonsists of all theories with Yukawa coupling in which the vacuum polarization is neglected. The method used is that of comparison with the exactiy solvable neutral sealar model.
