“…Ultraviolet stability of three-and four-dimensional non-Abelian lattice gauge theories by phase cell renormalization, as outlined above, was famously established by Ba laban (1983, 1984a,b,c,d, 1985a,b,c,d,e, 1987, 1988, 1989a,b) in a long series of papers spanning six years. A somewhat different approach, again using phase cell renormalization, was pursued by Federbush (1986Federbush ( , 1987aFederbush ( ,b, 1988Federbush ( , 1990 and Federbush and Williamson (1987).…”
