In the unitary gauge one recovers the original formulation. Although this gauging mechanism can be extended to noncommutative spaces in a straightforward way, non trivial aspects show up when we consider the Seiberg-Witten map. As we show here, only a particular class of its solutions leads to an action that admits the unitary gauge fixing.General solutions for the map and important reference included, 6 pages, no figuresHigh Energy Physics - TheoryNonequivalent Seiberg-Witten maps for noncommutative massive U(N) gauge theorytext
