Symmetries of order eight on K3 surfaces without high genus curves in the fixed locus
Dima Al Tabbaa, Annalisa Grossi, Alessandra Sarti
In this paper we classify non-symplectic automorphisms of order 8 on complex K3 surfaces in case that the fourth power of the automorphism has only rational curves in its fixed loc…
