Strongly ambiguous Hilbert squares of projective K3 surfaces with Picard number one

Algebraic Geometry 2019-12-13 v1

Abstract

We provide a criterion for when Hilbert squares of complex projective K3 surfaces with Picard number one are strongly ambiguous. This criterion is the same as [DM, Proposition 3.14], but is obtained by a different method. In particular, this enables us to compute the automorphism groups of these Hilbert squares from a different point of view with respect to [BCNS].
