Virasoro-似代数的分次模

Graded modules for Virasoro-like algebra

Weiqiang Lin, Yucai Su

摘要:

本文考虑Virasoro-like代数上具有有限维齐次子空间的不可约${\bf Z}$ -和${\bf Z}^2$ -分次模的分类.我们首先证明了这样的模是一致有界模或广义最高权模。然后确定了所有广义最高权不可约模。作为结果,我们也确定了所有的模与非零中心。最后证明了不存在中间级数的非平凡${\bf Z}$ -分次模.

英文摘要:

In this paper, we consider the classification of irreducible ${\bf Z}$- and ${\bf Z}^2$-graded modules with finite dimensional homogeneous subspaces over the Virasoro-like algebra. We first prove that such a module is a uniformly bounded module or a generalized highest weight module. Then we determine all generalized highest weight irreducible modules. As a consequence, we also determine all the modules with nonzero center. Finally, we prove that there does not exist any nontrivial ${\bf Z}$-graded modules of intermediate series.
