The consequences of this possibility for the general space A of gauge potentials are examined. Any two potentials are connected by a straight line in A, but a straight line going through two copies either contains no other copy or is entirely formed by copies.7 pages, revtex4Mathematical Physics57R22;55R10;32L81Wu-Yang ambiguity in connection spacetext
