摘要
利用李代数L=m∈Z(CLmCEm)包含无中心的Virasoro代数(Witt代数)作为李代数L的子代数,研究L的导子和中心扩张等问题.结果表明L是一个无限维的Complete李代数并且L的泛中心扩张在Leibniz代数范畴与李代数范畴是相同的.
Derivations and universal central extensions of the Lie algebra L were studied using the Lie algebra where L = +m∈Z(CLm + CEm) which contains the centerless Virasoro algebra (Witt algebra) as a subalgebra. It is proved that L is a complete infinite-dimensional Lie algebra and the universal central extension of L in the category of Leibniz algebras is the same as that in the category of Lie algebras.
