A COHOMOLOGICAL APPROACH TO THE BATALIN, LAVROV, TYUTIN COVARIANT QUANTIZATION OF IRREDUCIBLE GAUGE THEORY

摘要

The anti-BRST transformation for an arbitrary irreducible gauge invariant action is implemented in the usual Batalin-Vilkovisky (sv) approach. This is done without duplicating the gauge symmetries, but rather by duplicating all fields and antifields of the theory. fn this way the Sp(2)-covariant quantization can be accomplished in the standard sv approach and its equivalence with the Batalin-Lavrov-Tyutin (BLT) approach is proved by a special gauge-fixing procedure.
