REVISED FINITE FIELD-DEPENDENT BRST FORMULATION

Keywords: Symmetry, Gauge theory.
We present a simplified version of well-known finite field-dependent Becchi-Rouet-Stora-Tyutin (FFBRST) formulation advocated originally in Ref. . In the present approach we don’t require any ansatz for local functional in order to compute the Jacobian corresponding to functional measure which satisfies certain boundary conditions. We show the equivalence of our approach to the original one, by producing the same results obtained by the original method, in two explicit examples. In the first example, we build the connections between Lorentz and axial gauges in Yang-Mills theory. However, in the second example, we relate the covariant and non-covariant gauges of the Abelian antisymmetric rank-2 tensor field theory.
