本文对满Toroidal李代数和高维Virasoro代数上的不可约Harish-Chandra模进行了分类,揭示了其结构特征。

摘要:

在本文中,我们对满Toroidal李代数上的不可约Harish-Chandra模进行了分类,该代数是Affine-Virasoro代数的自然高维推广。特别是,我们完成了不可约有界模的分类,这些模曾由Billig在非零级数模的情况下研究过[Int. Math. Res. Not. 2006]。作为副产品,我们还获得了对高维Virasoro代数上不可约Harish-Chandra模的分类,该代数由Rao-Moody引入[Comm. Math. Phys. 1994],从而推广了O.Mathieu对于经典Virasoro代数的著名结果[Invent. Math. 1992]。更具体地说,我们证明了任何高维Virasoro代数上的不可约Harish-Chandra模要么是张量场在环面上的模的商,要么是最高权型模在自同构的扭曲下。这一结论与Eswara Rao于2004年的猜想一致。

英文摘要:

In this paper, we classify the irreducible Harish-Chandra modules over the full toroidal Lie algebra, which is a natural higher-dimensional analogue of the affine-Virasoro algebra. In particular, we complete the classification of irreducible bounded modules, which were studied by Billig for non-zero level modules [Int. Math. Res. Not. 2006]. As a by-product, we also obtain the classification of irreducible Harish-Chandra modules over the higher-dimensional Virasoro algebra, which was introduced by Rao-Moody [Comm. Math. Phys. 1994], thereby generalizing the well-known result of O. Mathieu [Invent. Math. 1992] for the classical Virasoro algebra. More precisely, we show that any irreducible Harish-Chandra module over the higher-dimensional Virasoro algebra turns out to be either a quotient of a module of tensor fields on a torus or a highest weight type module up to a twist of an automorphism, as conjectured by Eswara Rao in 2004.
