摘要 C_q∶=C_q[x_1^(±1),x_2^(±1)]为复数域上的量子环面,其中q≠0是一个非单位根,D(C_q)为C_q的导子李代数.记L_q为C_q(?)D(C_q)的导出子代数.该文研究李代数L_q的自同构群,泛中心扩张和导子李代数. Let q be generic and Cq:= Cq[x1^±1, x2^±1] be an associative torus algebra, and D(Cq) the set of derivations of Cq. Set Lq to be the derived Lie subalgebra of Cq+D(Cq). In this paper, we study the automorphism group, central extension and derivations of the Lie algebra Lq.
