本文研究了Nappi-Witten模型H4的仿射李代数H <$4的表示理论.我们对H_∞ ~ 4的所有不可约最高权模进行了分类。进一步,我们给出了每个H <$4-(广义)Verma模不可约的充要条件.对于可约的奇异向量,我们刻画了所有线性无关的奇异向量。最后,我们构造了这些李代数的Wakimoto型模,并用顶点算子代数及其模来解释这种构造。
In this paper, we study the representation theory for the affine Lie algebra Hˆ4associated to the Nappi–Witten model H4. We classify all the irreducible highest weight modules of Hˆ4. Furthermore, we give a necessary and sufficient condition for each Hˆ4-(generalized) Verma module to be irreducible. For reducible ones, we characterize all the linearly independent singular vectors. Finally, we construct Wakimoto type modules for these Lie algebras and interpret this construction in terms of vertex operator algebras and their modules.
