摘要：

We present a formulation of non-Abelian gauge theories in general axial gauges using a Wilsonian (or 'Exact') Renormalisation Group. No 'spurious' propagator divergencies an encountered in contrast to standard perturbation theory. Modified Ward identities, compatible with the flow equation, ensure gauge invariance of physical Green functions. The axial gauge nA = 0 is shown to be a fixed point under the now equation. Possible non-perturbative approximation schemes and further applications are outlined. (C) 1998 Elsevier Science B.V. All rights reserved.
