摘要：

We describe in detail the constrained procedure of differential renormalization and develop the techniques required for one-loop calculations. As an illustration we renormalize scalar QED and show that the two-, three- and four-point Ward identities are automatically satisfied. (C) 1999 Elsevier Science B.V.
