Query: Kummer rigidity for K3 surface automorphisms via Ricci-flat metrics   We give an alternative proof of a result of Cantat and Dupont, showing that
any automorphism of a K3 surface with measure of maximal entropy in the
Lebesgue class must be a Kummer example. Our method exploits the existence of
Ricci-flat metrics on K3s and also covers the non-projective case.
