Abstract
We show that in the hamiltonian formalism of compact QED on the lattic e gauge transformations appear as representations of translations on a circle or on a line according to the boundary conditions on the wave functions. When gauge invariance is enforced, one gets at strong coupl ing a linear potential in the first case and a Coulombic potential in the second.
