设$\mathcal{O}$是Jimbo和第一作者引入的量子仿射代数的Borel子代数的表示范畴。我们证明了$\mathcal{O}$的某个monoidal子范畴的Grothendieck环具有无限秩的簇代数的结构,初始种子由prefundamental表示组成.特别是,著名的巴克斯特关系的6顶点模型得到解释为Fomin-Zelevinsky突变关系。
Let $\mathcal{O}$ be the category of representations of the Borel subalgebra of a quantum affine algebra introduced by Jimbo and the first author. We show that the Grothendieck ring of a certain monoidal subcategory of $\mathcal{O}$ has the structure of a cluster algebra of infinite rank, with an initial seed consisting of prefundamental representations. In particular, the celebrated Baxter relations for the 6-vertex model get interpreted as Fomin-Zelevinsky mutation relations.
