摘要:考虑具有标准生成元的复矩阵李超代数,其中.定义By的对合自同构η。扭曲多项式当前李超代数 具有自然李余超代数结构。我们把泛包络代数量化为余Poisson-Hopf超代数。对于量子化的代数,我们给出了中心的描述,并构造了Drinfeld意义下的二重数。我们还构造了量子化代数的一类广泛的不可约表示。
Abstract:Consider the complex matrix Lie superalgebra with the standard generators , where . Define an involutory automorphism η of by . The twisted polynomial current Lie superalgebra has a natural Lie co-superalgebra structure. We quantise the universal enveloping algebra as a co-Poisson Hopf superalgebra. For the quantised algebra we give a description of the centre, and construct the double in the sense of Drinfeld. We also construct a wide class of irreducible representations of the quantised algebra.
