设$ g子集SL_2(C)子集SL_3(C)$是一个有限群。我们计算了$C^3/G$的渐进分辨率$Hilb^G(C^3)$的动机Pandharipande-Thomas和Donaldson-Thomas不变量,推广了Gholampour和Jiang使用局部化技术计算数值DT/PT不变量的结果。我们的公式依赖于一类特殊的带势颤振的动机Donaldson-Thomas不变量的计算。我们证明了这些动机Donaldson-Thomas不变量与Kac在有限域上引入的绝对不可分解颤振表示的多项式密切相关。我们给出了一类广义的带势颤子的Donaldson-Thomas不变量正性的一个猜想。这个猜想,如果成立,就意味着对于任意振动的Kac正猜想。
Let $Gsubset SL_2(C)subset SL_3(C)$ be a finite group. We compute motivic Pandharipande-Thomas and Donaldson-Thomas invariants of the crepant resolution $Hilb^G(C^3)$ of $C^3/G$ generalizing results of Gholampour and Jiang who computed numerical DT/PT invariants using localization techniques. Our formulas rely on the computation of motivic Donaldson-Thomas invariants for a special class of quivers with potentials. We show that these motivic Donaldson-Thomas invariants are closely related to the polynomials counting absolutely indecomposable quiver representations over finite fields introduced by Kac. We formulate a conjecture on the positivity of Donaldson-Thomas invariants for a broad class of quivers with potentials. This conjecture, if true, implies the Kac positivity conjecture for arbitrary quivers.
