We show a relation between the regularization ambiguities and the coupling parameters of the theory as well as their role in the implementation of a local gauge symmetry at quantum level.1933-1938engtheory of quantized fieldsgauge field theoriessymmetry and conservation lawsArtigo10.1142/S0217732305017044WOS:000231328300008Acesso restrito
