设${mathcal{A}}$是有限维复杂代数上的模的范畴。我们证明了${mathcal{A}}$上的稳定性条件的空间参数化了一个等价于${mathcal{A}}$的Hall代数的不规则连接族。这些连接的残数由D. Joyce (in Geom)构造的${mathcal{A}}$中计数不变量的全纯生成函数给出。Topol. 11, 667-725, 2007)。
Let ${mathcal{A}}$ be the category of modules over a complex, finite-dimensional algebra. We show that the space of stability conditions on ${mathcal{A}}$ parametrises an isomonodromic family of irregular connections on ℙ1 with values in the Hall algebra of ${mathcal{A}}$. The residues of these connections are given by the holomorphic generating function for counting invariants in ${mathcal{A}}$ constructed by D. Joyce (in Geom. Topol. 11, 667–725, 2007).
