Sp(2)-symmetric langrangian BRST quantization Original Research Article

One lagrangian BRST quantization principle is that of imposing correct Schwinger-Dyson equations through the BRST Ward identities. In this paper we show how to derive the analogous Sp(2)-symmetric quantization condition in flat coordinates from an underlying Sp(2)-symmetric Schwinger-Dyson BRST symmetry. We also show under what conditions this can be recast in the language of triplectic quantization.
