Abstract
fter reviewing Gribov ambiguity of non-Abelian gauge theories, a phenomenon relatedto the topology of the bundle of gauge connections, we show that there is a similar feature fornoncommutative QED over Moyal space, despite the structure group being Abelian, and weexhibit an infinite number of solutions for the equation of Gribov copies. This is a genuineeffect of noncommutative geometry which disappears when the noncommutative parametervanishes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
