量子环面上skew导子李代数的中心扩张

Central extention of the Lie algebras of skew derivations for the quantum torus

研究了量子环面上的斜导子李代数的中心扩张,重新构造了■,使得它是L的泛中心扩张,并给出了比Lin(直接应用定义进行证明[1])更简要的证明.

In this paper, we study the central extensions of the Lie algebra of skew derivations for the quantum torus, and renew construct L, make it the universal central extension of L, and give more simplified proof of the results than Lin （who prove that results direedy）.
