Abstract
We show that the two phases of the 4-dimensional compact U(1) lattice gauge theory are characterized by the existence or absence of an infin ite current network, defining ''infinite'' on a finite lattice in a ma nner appropriate to the chosen boundary conditions. In addition for op en and fixed boundary conditions we demonstrate the effects of inhomog eneities and provide examples of the reappearance of an energy gap.
