The Gribov problem in Noncommutative QED
arXiv:1505.06342 · doi:10.1007/JHEP01(2016)014
Abstract
It is shown that in the noncommutative version of QED (NCQED) Gribov copies induced by the noncommutativity of space-time appear in the Landau gauge. This is a genuine effect of noncommutative geometry which disappears when the noncommutative parameter vanishes.
