Аннотация:This paper discusses some interesting features of quantum corrections in N = 1 supersymmetric theories, which have been discovered analyzing calculations made with the higher covariant derivative regularization. In particular, the author argues that all integrals, defining the Gell-Mann-Low function in supersymmetric theories, are integrals of total derivatives. As a consequence, possibly there are some interesting identities, which restrict Green functions and do not follow from usual Slavnov-Taylor identities.
