Involutions on the Hilbert square of a K3 surface

Abstract: I will use K3 surfaces with special geometry to construct involutions on the Hilbert square of a K3 surface. The existence of such involutions can be proven using the Torelli theorem for hyper-Kaehler manifolds, but it is a challenging problem to produce concrete realizations.
