Abstract
Let be a smooth projective rational surface, an effective anticanonical curve, a curve class on and an effective divisor on . We consider the moduli space of sheaves on which are direct images of rank- torsion-free sheaves on integral curves in such that , and show that each point of is smooth over a point in the product of the Hilbert schemes of surface singularities of types . Hence, has symplectic singularities and admits a unique symplectic resolution.
