利用代数重写方法研究了量子群的Khovanov-Lauda-Rouquier候选2-范畴化的一种表示。我们使用的计算方法的基础上重写模的合痕公理的枢轴结构,计算家庭的线性基地的所有向量空间的2细胞的2类。我们表明,这些基地对应于Khovanov和劳达的约束生成集,证明了非退化的图解演算。这意味着这个2-范畴是Lusztig的幂等整数量子群Uq(g)与可对称化的单缀Kac-Moody代数g相关联的范畴。
We study a presentation of the Khovanov-Lauda-Rouquier's candidate 2-categorification of a quantum group using algebraic rewriting methods. We use a computational approach based on rewriting modulo the isotopy axioms of its pivotal structure to compute a family of linear bases for all the vector spaces of 2-cells of this 2-category. We show that these bases correspond to Khovanov and Lauda's conjectured generating sets, proving the non-degeneracy of their diagrammatic calculus. This implies that this 2-category is a categorification of Lusztig's idempotented and integral quantum group U q (g) associated with a symmetrizable simply-laced Kac-Moody algebra g.
