On Chow groups of some hyperkähler fourfolds with a non-symplectic involution. II. (English) Zbl 1402.14008

Summary: This note is about hyperkähler fourfolds \(X\) admitting a non-symplectic involution \(\iota\). The Bloch-Beilinson conjectures predict the way \(\iota\) should act on certain pieces of the Chow groups of \(X\). The main result of this note is a verification of this prediction for Fano varieties of lines on certain cubic fourfolds. This has some interesting consequences for the Chow ring of the quotient \(X/\iota\).
