Gap theorems and achirality for automorphisms of K3 surfaces and Enriques surfaces

Kohei Kikuta, Yuta Takada, Taiki Takatsu

We prove gap theorems for entropy norms on automorphism groups of K3 surfaces, Enriques surfaces, and irreducible holomorphic symplectic manifolds. We also study the achirality of…

Dynamical degrees of automorphisms of K3 surfaces with Picard number 2

Yuta Takada

We show that there exists an automorphism of a projective K3 surface with Picard number $2$ such that the trace of its action on the Picard lattice is $3$ . Together with a result o…

Unboundedness of fixed point multiplicities on a K3 surface

Kenji Hashimoto, Yuta Takada

We exhibit automorphisms of a certain K3 surface in $P^{1} \times P^{1} \times P^{1}$ with an isolated fixed point at which the induced action on the stalk of t…
