Renormalization group approach to lattice gauge field theories. I: Generation of effective actions in a small field approximation and a coupling constant renormalization in four dimensions
The author studies four-dimensional pure gauge field theories by the renormalization group approach. The analysis is restricted to small field approximation. In this region he constructs a sequence of localized effective actions by cluster expansions in one step renormalization transformations. He also defines a coupling constant renormalization by a recursive system of renormalization group equations.
