Attractor-invariant formula under quiver mutation

At least 5 years old · documented by

Let (Q,W)(Q,W) and (Q′,W′)(Q',W') be quivers with potential related by mutation at a vertex kk, and let d,d′d,d' and stability weights θ,θ′\theta,\theta' be related by the mutation formulas in the source. Let Ωθ(d,y)\Omega_\theta(d,y) and Ωθ′′(d′,y)\Omega'_{\theta'}(d',y) be the corresponding DT invariants. Suppose that dd is not collinear to eke_k, equivalently that d′d' is not collinear to ek′e'_k. Attractor-invariant mutation conjecture. If d∈NQ0d\in\mathbb{N}^{Q_0} and d′∈NQ0′d'\in\mathbb{N}^{Q'_0}, then Ωθ(d,y)=Ωθ′′(d′,y)\Omega_\theta(d,y)=\Omega'_{\theta'}(d',y); if d∈NQ0d\in\mathbb{N}^{Q_0} but d′∉NQ0′d'\notin\mathbb{N}^{Q'_0}, then Ωθ(d,y)=0\Omega_\theta(d,y)=0; and if d′∈NQ0′d'\in\mathbb{N}^{Q'_0} but d∉NQ0d\notin\mathbb{N}^{Q_0}, then Ωθ′′(d′,y)=0\Omega'_{\theta'}(d',y)=0. In particular, the attractor invariants coincide or vanish under the same conditions. This expresses the expected mutation, or Seiberg-duality, invariance of DT invariants away from the mutated basis direction; the source gives no resolution status.
