Abstract
Photon correlators in U(1) pure gauge theory for different lattice act ions are considered under the Lorentz gauge condition. They are shown to depend strongly on the gauge fixing ambiguity and on the correspond ing existence of Dirac sheets. For the Coulomb phase a gauge fixing al gorithm is proposed which avoids Dirac sheets and allows to find the g lobal extremum of the non-local gauge condition.
