Descripción
We discuss in detail the implementation of a Wilsonian RG for gauge theories. This is then applied to QCD in axial gauges to show -amongst others- that the spurious propagator divergences of pert. theory are absent. For thermal QCD we construct a gauge invariant flow for thermal fluctuations.
