Exact renormalization group in algebraic noncovariant gauges

I study a class of Wilsonian formulations of non-Abelian gauge theories in algebraic noncovariant gauges where the Wilsonian infrared cutoff Lambda is inserted as a mass term for the propagating fields. In this way the Ward-Takahashi identities are preserved to all scales. Nevertheless the BRS-invariance in broken and the theory is gauge-dependent and unphysical at Lambda not equal 0. Then I discuss the infrared limit Lambda not equal 0. I show that the singularities of the axial gauge choice are avoided in planar gauge and in light-cone gauge. Finally the rectangular Wilson loop of size 2L x 2T is evaluated at lowest order in perturbation Cheery and a noncommutativity between the limits Lambda --> 0 and T --> infinity is pointed out.
