Note: There appears to be a serious error in this paper, in Theorem 1: a field A which is a critical point (or extremiser) for the Yang-Mills functional when restricted to a special subclass of fields, is not necessarily a critical point for the functional for all fields, and in particular is not necessarily a solution to the Yang-Mills equation.
