设Uq(g)是对应于半单李代数g的量子化包络代数.我们描述的算法,以获得乘法表的PBW型基的Uq(g)。我们利用这一点得到了一个算法,用于计算子代数U?中理想的Grobner基,这导致了Uq(g)上不可约最高权模的一般构造。我们还指出如何计算相应的R -矩阵。
Let Uq(g) be the quantized enveloping algebra corresponding to the semisimple Lie algebra g. We describe algorithms to obtain the multiplication table of a PBW-type basis of Uq(g). We use this to obtain an algorithm for calculating a Grobner basis of an ideal in the subalgebra U?, which leads to a general construction of irreducible highest-weight modules over Uq(g). We also indicate how to compute the corresponding R -matrices.
