我们证明了量子DT-不变量与quivers与优雅的潜在的可以表示在某些精炼计数的热带磁盘。这是基于量子版本的Bridgeland的描述集群散射图的稳定性条件,加上一个新版本的描述散射图的热带磁盘计数。计算热带盘的权重用某些旗形变种的动机积分来表示。我们还通过明确的反例表明,霍尔代数折线不会导致一致的霍尔代数θ函数,即,它们违反了Carl-Pumperla-Siebert引理在经典环境下的推广。
We prove that the quantum DT-invariants associated to quivers with genteel potential can be expressed in terms of certain refined counts of tropical disks. This is based on a quantum version of Bridgeland’s description of cluster scattering diagrams in terms of stability conditions, plus a new version of the description of scattering diagrams in terms of tropical disk counts. The weights with which the tropical disks are counted are expressed in terms of motivic integrals of certain quiver flag varieties. We also show via explicit counterexample that Hall algebra broken lines do not result in consistent Hall algebra theta functions, i.e., they violate the extension of a lemma of Carl–Pumperla–Siebert from the classical setting.
