The symplectic-singularity conjecture for multiplicative quiver varieties

Let $\mathcal{M}_{q,\theta}(Q,\alpha)$ denote a multiplicative quiver variety. A symplectic singularity is a normal singular variety whose smooth locus carries a symplectic form extending to a regular two-form on every resolution. Symplectic-singularity conjecture. Every multiplicative quiver variety is a symplectic singularity. This would place multiplicative quiver varieties within the general framework of symplectic singularities and support the expected analysis of their symplectic resolutions; the statement remains open in the source.
