Abstract

Description

The gauge independence in connection with the UV/IR-mixing is discussed with the help of the non-commutative U(1)-gauge field model proposed by A. A. Slavnov with two different gauges: the covariant gauge fixing defined via a gauge parameter αand the non-standard axial-gauge depending on a fixed gauge direction n^μ.
