摘要：

The Gribov ambiguity problem is studied for compact U(1) lattice theory within the Lorentz gauge. In the Coulomb phase, it is shown that apart from double Dirac sheets Gribov copies originate mainly from zero-momentum modes of the gauge fields. nle removal of the zero-momentum modes is necessary for reaching the absolute maximum of the Lorentz gauge functional.
