We investigate the problem of perfectly preserving a symmetry associated naturally with one coordinate system when calculated in a different coordinate system. This allows a much wider range of problems that may be viewed as perturbations of the given symmetry to be investigated. We study the proble
We present a prescription to define quadratically and logarithmically divergent parts of several integrals employing a cut-off in agreement with some symmetry requirements. As examples we consider one-loop Ward identities for QED and a phenomenological chiral model.
