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.LaTeX, 19 pagesHigh Energy Physics - TheorySp(2)-Symmetric Lagrangian BRST Quantizationtext
