Automorphisms of Hilbert schemes of Cayley's K3 surfaces
Kwangwoo Lee
We prove that the automorphism group of Hilbert square of a Cayley's K3 surface of Picard number 2 is the free product of three cyclic groups of order two. The generators are three…
Free automorphism groups of K3 surfaces with Picard number 3
Kenji Hashimoto, Kwangwoo Lee
It is known that the automorphism group of any projective K3 surface is finitely generated [24]. In this paper, we consider a certain kind of K3 surfaces with Picard number 3 whose…
K3 surfaces with Picard number two
Kwangwoo Lee
It is known that an automorphism group of a K3 surface with Picard number two is either infinite cyclic group or infinite dihedral group if it is infinite. In this paper, we study…
K3 surfaces with Picard number 2, Salem polynomials and Pell equation
Kenji Hashimoto, JongHae Keum, Kwangwoo Lee
If an automorphism of a projective K3 surface with Picard number 2 is of infinite order, then the automorphism corresponds to a solution of Pell equation. In this paper, by solving…
