Donaldson-Thomas型不变量的模、函数方程和积分的上同调

Cohomology of quiver moduli, functional equations, and integrality of Donaldson-Thomas type invariants

Markus Reineke

摘要:

导出了一组函数方程,它将箭图稳定表示的模空间的欧拉示性数与箭图模的(Hilbert格式型)框架形式的欧拉示性数联系起来。这适用于M的Donaldson-Thomas型不变量的跨壁公式。Kontsevich和Y. Soibelman,特别是确认其完整性。

英文摘要:

A system of functional equations relating the Euler characteristics of moduli spaces of stable representations of quivers and the Euler characteristics of (Hilbert scheme-type) framed versions of quiver moduli is derived. This is applied to wall-crossing formulas for the Donaldson-Thomas type invariants of M. Kontsevich and Y. Soibelman, in particular confirming their integrality.
