Abstract
We consider the gauge potential A and argue that the minimum value of the v olume integral of A(2) (in Euclidean space) may have physical meaning, part icularly in connection with the existence of topological structures. A latt ice simulation comparing compact and noncompact "photodynamics" shows a jum p in this quantity at the phase transition, supporting this idea.
