摘要:

Cq:=Cq[x±11, x±12] 为复数域上的量子环面, 其中q≠ 0是一个非单位根, D(Cq) 为Cq的导子李代数. 记Lq Cq D(Cq)的导出子代数. 该文研究李代数Lq的自同构群, 泛中心扩张和导子李代数.

关键词: 李代数, 量子环面, 自同构群, 泛中心扩张, 导子

Abstract:

Let q be generic and Cq:=x±11, x±12] be an associative torus algebra, and D(Cq) the set of derivations of Cq. Set Lq to be the derived Lie subalgebra of CqD (Cq). In this paper, we study the automorphism group, central extension and derivations of the Lie algebra Lq.

Key words: Lie algebra, Quantum torus, Automorphism group, Central extension, Derivations
