我们推导出m-圈箭图的量子化Donaldson-Thomas不变量的组合公式。我们的主要工具是非对易Hilbert格式的组合学和这个箭图的上同调Hall代数的简并版本。
We derive a combinatorial formula for quantized Donaldson-Thomas invariants of the m-loop quiver. Our main tools are the combinatorics of noncommutative Hilbert schemes and a degenerate version of the Cohomological Hall algebra of this quiver.
