设Q是任意无定向圈的有值环。我们研究了量子团簇代数中Q的值表示范畴与团簇变量关于初始团簇的展开之间的联系。我们表明,类似的Caldero-Chapoton公式持有的专业化,其中是一个有限的字段,在所有的量子集群代数的有限类型,包括非简单的花边类型,并为任何集群变量在一个几乎无环集群。
Let Q be any valued quiver without oriented cycles. We study connections between the category of valued representations of Q and expansions of cluster variables in terms of an initial cluster in quantum cluster algebras. We show that an analog of the Caldero–Chapoton formula holds for the specializations , where is a finite field, in all quantum cluster algebras of finite type, including nonsimply laced types, and for any cluster variable in an almost acyclic cluster.
