摘要
本文对WZNW模型的各种共形约化导致的W代数间可能的同构关系作了研究,给出了W代数同构性的判据。在sl_3的情形,我们对W[(111)_2]与W[(12)_1]的同构性作了明显的证明,并讨论了在同构变换下它们的O'Raifeartaigh规范间的约束-规范条件相互转化以及共形谱的改变等问题。
The possible isomorphic relations between W algebras from various conformal reductions of WZNW model are investigated and the criterion for the isomorphism of W algebrasis given. In the special case of sl_3 WZNW theory, we show explicitly the isomorphism between W[(111)_2] and W[(12)_1] and discuss the constraint-gauge condition transmutation between the O'Raifeartaigh gauges and the transmutation of conformal weights under the isomorphism transformation.
