%0 Journal Article %T Concerning gauge field fluctuations around classical configurations %A Dennis D. Dietrich %J Physics %D 2009 %I arXiv %R 10.1103/PhysRevD.79.107703 %X We treat the fluctuations of non-Abelian gauge fields around a classical configuration by means of a transformation from the Yang--Mills gauge field to a homogeneously transforming field variable. We use the formalism to compute the effective action induced by these fluctuations in a static background without Wu--Yang ambiguity. %U http://arxiv.org/abs/0904.0820v2
