Finite field-dependent BRS (FFBRS) transformation is a generalization
of ordinary BRS transformation that can be used to connect actions in
different gauge. In this work, we develop the FFBRS transformation tha
t connects the usual Lorentz gauges (with gauge parameter lambda) with
axial gauges (with gauge parameter lambda'). We suggest a possible ap
plication of this result to rigorously obtain the prescription of the
1/eta . q type singularity.
