Abstract We apply the wall-crossing structure formalism of Kontsevich and Soibelman to Seiberg–Witten integrable systems associated to pure S U ( 3 ) . This gives an algorithm for computing the Donaldson–Thomas invariants, which correspond to BPS degeneracy of the corresponding BPS states in physics. The main ingredients of this algorithm are the use of split attractor flows and Kontsevich–Soibelman wall-crossing formulas. Besides the known BPS spectrum in pure S U ( 3 ) case, we obtain new family of BPS states with BPS-invariants equal to 2.

穿墙结构及其在 SU(3) Seiberg-Witten 可积系统中的应用

摘要 我们将 Kontsevich 和 Soibelman 的穿墙结构形式主义应用于与纯 SU (3) 相关的 Seiberg-Witten 可积系统。这给出了一种计算 Donaldson-Thomas 不变量的算法,它对应于物理学中相应 BPS 状态的 BPS 简并。该算法的主要成分是使用分裂吸引子流和 Kontsevich-Soibelman 穿墙公式。除了纯 SU (3) 情况下的已知 BPS 谱外,我们还获得了 BPS 不变量等于 2 的新 BPS 状态族。
