Zero-cycles and the Cayley-Oguiso automorphism

Algebraic Geometry 2024-04-23 v1

Abstract

Cayley and Oguiso have constructed certain quartic K3 surfaces SS, with automorphisms gg of infinite order. We show that when gg is symplectic (resp. anti-symplectic), it acts as the identity (resp. minus the identity) on the degree zero part of the Chow group of zero-cycles of SS.
