Brundan和Kleshchev最近给出了广义线性李代数gl_n的Yangian Y(gl_n)的一族新的表示,从而为它的研究提供了一个新的途径.在这篇文章中,我们展示了如何他们的一些想法可以卓有成效地推广到考虑Yangian Y(gl_{m| n})与李超代数gl_{m| n}。特别地,我们给出了Nazarov的结果,量子Berezinian是中心的一个新的证明。
Brundan and Kleshchev recently introduced a new family of presentations of the Yangian Y(gl_n) associated to the general linear Lie algebra gl_n, and thus provided a fresh approach to its study. In this article, we show how some of their ideas can be fruitfully extended to consider the Yangian Y(gl_{m|n}) associated to the Lie superalgebra gl_{m|n}. In particular, we give a new proof of the result by Nazarov that the quantum Berezinian is central.
