Abstract
Exact renormalization group techniques are applied to the mass deformed N = 4 supersymmetric Yang{Mills theory, viewed as a regularized N = 2 model. The solution of the flow equation, in case of dominance of the potential term, reproduces the one-loop (perturbatively exact) expression for the eective action of N = 2 supersymmetric Yang-Mills theory, when the regularizing mass, M, reaches the value of the dynamical cutoff. One speculates about the way in which further nonperturbative contributions (instanton eects) may be accounted for.File in questo prodotto:
