| 中文摘要: |
| Hom-李代数是一类满足反对称和Hom-Jacobi等式的非结合代数.扭Heisenberg-Virasoro代数是次数不超过1的微分算子代数的中心扩张,它是一类重要的无限维李代数, 与一些曲线的模空间有关.文章主要研究扭Heisenberg-Virasoro 代数上Hom-李代数结构,确定了扭Heisenberg-Virasoro代数上存在非平凡的Hom-李代数结构. |
| 英文摘要: |
| Hom-Lie algebra is an anticommutative algebra with a multiplication such that the Hom-Jacobi identity holds. The twisted Heisenberg-Virasoro algebra L is the universal central extension of the Lie algebra W of differential operators of order at most one, which is connected with certain moduli spaces of curves. This paper mainly determines all Hom-Lie algebra structures on the twisted Heisenberg-Virasoro algebra L and gets some nontrivial Hom-Lie algebra structures on L. |
