Let (X, H) be a polarized smooth projective surface satisfying H1(Χ, OΧ) = 0, and let Ƒ be either a rank 1 torsion-free sheaf or a rank 2 μH-stable vector bundle on Χ. Assume that c1(Ƒ) ≠ 0. This article shows that the rank 2—respectively, rank 4—tautological sheaf Ƒ[2] associated with Ƒ on the Hilbert square Χ[2] is μ-stable with respect to a certain polarization.
