On the action of symplectic automorphisms on the CH0-groups of some hyper-K\"ahler fourfolds

Abstract

We prove that for any polarized symplectic automorphism of the Fano variety of lines of a cubic fourfold (equipped with the Pl\"ucker polarization), the induced action on the Chow group of 0-cycles is identity, as predicted by Bloch-Beilinson conjecture.
