Covariant Quantization with Extended BRST Symmetry
arXiv:hep-th/9911176
Abstract
A short rewiev of covariant quantization methods based on BRST-antiBRST symmetry is given. In particular problems of correct definition of Sp(2) symmetric quantization scheme known as triplectic quantization are considered.
