基于“正部分”的量子洗牌构造的精神,我们给出了与可对称化的Kac-Moody李代数相关的整个量子群作为量子拟对称代数的构造,这是多支撑余张量Hopf代数的一种特殊情况。所有最高权重的不可约表示都是使用该机器构造的。它还提供了一种在量子群的量子对上构造简单模的系统方法。
We give a construction of the whole quantum group associated to a symmetrizable Kac-Moody Lie algebra as a quantum quasi-symmetric algebra, a particular case of multi-brace cotensor Hopf algebras, in the spirit of the quantum shuffle construction of the “plus part”. All highest weight irreducible representations are constructed using this machinery. It also provides a systematic way to construct simple modules over the quantum double of a quantum group.
