根据德林菲尔德的一般格式,我们描述了一般线性李代数glnn的二重Yangian。我们还利用Yangian的Hopf代数结构描述了Yangian的中心,并在其表示理论的基础上证明了poincar<s:1> - birkhoff - witt定理对Yangian的类似性。这个证明可以推广到双阳历。
We describe the double Yangian of the general linear Lie algebra glNby following a general scheme of Drinfeld. We also describe the centre of the Yangian by using its Hopf algebra structure, and provide a proof of the analogue of the Poincaré—Birkhoff—Witt theorem for the Yangian based on its representation theory. This proof extends to the double Yangian.
