摘要翻译:
我们首先构造了仿射三重曲面Calabi-Yau的小折皱分辨率与一个具有超势的颤振之间的一个导出的等价性。在此等价性下,我们建立了反常相干系统计数不变量母函数的穿墙公式。作为应用,我们给出了关于Donaldson-Thomas,Pandeharipande-Thomas和Szendroi不变量的一些方程。最后,我们证明了通过改变稳定性条件,与连续突变给出的颤振相关的模空间被实现为与原始颤振相关的模空间。

英文摘要:
We first construct a derived equivalence between a small crepant resolution of an affine toric Calabi-Yau 3-fold and a certain quiver with a superpotential. Under this derived equivalence we establish a wall-crossing formula for the generating function of the counting invariants of perverse coherent systems. As an application we provide certain equations on Donaldson-Thomas, Pandeharipande-Thomas and Szendroi's invariants. Finally, we show that moduli spaces associated with a quiver given by successive mutations are realized as the moduli spaces associated the original quiver by changing the stability conditions.
