Representation of BRS and full BRS algebra
Journal of Physics A: Mathematical and General, 1988BRS transformations (named after C. Becchi, A. Rouet, and R. Stora) are an important tool in the discussion of physical gauge theories. From a purely algebraic point of view they form the BRS or full BRS Lie superalgebra. The latter is just \({\mathfrak gl}(1| 1)/centre\), the former is one of the two isomorphic two-dimensional graded subalgebras with ...

After an analysis of the concept of Lagrangian gauge fixing, it is shown that the arbitrariness in the parametrization of gauge transformations gives rise to a whole family of classical BRS transformations. This is explicitly shown for the free-relativistic particle. Two inequivalent classes of BRS Lagrangians are defined.

BRS and anti-BRS symmetries in the planar gauge
Physical Review D, 1988The planar gauge is reexamined from various points of view. First, we find an annoying ambiguity in the definition of the product of two propagators. Second, Becchi-Rouet-Stora (BRS) invariance can be implemented only at the price of unavoidable second-order derivatives in the Lagrangian.
