研究了Yetter-Drinfel’ d范畴HH YD中李代数(即广义H-李代数)的表示,证明了广义H-李代数的Engel定理:设L是一个广义H-李代数,如果L的每一个循环Yetter-Drinfel’ d模都是ad-幂零的,那么L是幂零的。
It is studied that the representation of the Lie algebras in the Yetter-Drinfel’ d category HH YD( i.e.generalized H-Lie algebras) .The Engel’ s theorem for generalized H-Lie algebras is proved:Let L be a generalized H-Lie algebra, if every cyclic Yetter-Drinfel’ d submodule of L is ad-nilpotent, then L is nilpotent.
