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 为Cq ㈩ 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 Cq㈩ D (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
