Wall-crossing conjecture for self-dual Donaldson--Thomas invariants

Let (Q,W)(Q,W) be a self-dual quiver with potential, and let τ\tau and τ~\widetilde{\tau} be self-dual weak stability conditions on the associated self-dual abelian category. Let DTθsd(τ)\mathrm{DT}^{\mathrm{sd}}_\theta(\tau) denote the self-dual Donaldson--Thomas invariants, and let χˉ\bar{\chi}, χ~\widetilde{\chi}, χˉsd\bar{\chi}^{\mathrm{sd}}, and χ~sd\widetilde{\chi}^{\mathrm{sd}} denote the ordinary and self-dual Euler-form coefficients. Wall-crossing conjecture for self-dual Donaldson--Thomas invariants. For any two self-dual weak stability conditions, the invariants DTθsd(τ)\mathrm{DT}^{\mathrm{sd}}_\theta(\tau) satisfy the wall-crossing formula referenced in the source, with coefficients χˉ()\bar{\chi}({\cdots}), χ~()\widetilde{\chi}({\cdots}), χˉsd()\bar{\chi}^{\mathrm{sd}}({\cdots}), and χ~sd()\widetilde{\chi}^{\mathrm{sd}}({\cdots}) given by the corresponding coefficients for QQ regarded as a self-dual quiver without relations. The conjecture seeks the self-dual analogue of the established ordinary Donaldson--Thomas wall-crossing formula; no resolution is supplied in the source.
