On K3 surfaces with hyperbolic automorphism groups

Authors:  KOJI FUJIWARA, KEIJI OGUISO, XUN YU

Abstract

We show the finiteness of the N´eron-Severi lattices of complex projective K3 surfaces whose automorphism groups are non-elementary hyperbolic with explicit descriptions, under the assumption that the Picard number ≥ 6 which is optimal to ensure the finiteness. Our proof of finiteness is based on the study of genus one fibrations on K3 surfaces and recent work of Kikuta and Takatsu.
