Abstract: Dynamical symmetry breakings in quantum chromodynamics (QCD) are investigated by means of the renormalization-group equations and the Dyson equations. It is shown that: (1) The electromagnetic (and weak) interactions can not be neglected in studying those nonperturbative problems as dynamical symmetry breakings for type-A models in QCD. (2) When the electromagnetic interactions between stratons are taken into account in the weak coupling approximation, dynamical symmetry breakings in QCD occur for many realistic models (type-A models) with QCD asymptotically free. This conclusion may hold beyond the weak coupling approximation of the electromagnetic interactions if there can still be a self-consistent solution of Johnson-Baker-Willey in quantum electrodynamics or βe has an UV-stable fixed point. e∞≠0 (a simple zero of βe) and e∞is not too large.
