Comments on regularization ambiguities and local gauge symmetries
arXiv:hep-th/0412172 · doi:10.1142/S0217732305017044
Abstract
We study the regularization ambiguities in an exact renormalized (1+1)-dimensional field theory. 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.
