具体确定了一类中心为二维的三步幂零李代数的导子代数,得到了导子代数的一些性质,并证明了这类幂零李代数是可完备化幂零李代数。
In this paper we explicitly determine the derivation algebras of a class of 3-step nilpotent Lie algebras, and obtain some properties of the derivation algebras. It is proved that this class of nilpotent Lie algebras is a completable nilpotent Lie algebra.
