Automorphisms of positive entropy on some hyperKahler manifolds via derived automorphisms of K3 surfaces Ouchi, Genki


In this talk, I would like to give examples of projective hyperKahler manifolds of Picard number two with automorphisms of positive topological entropy. These are constructed as moduli spaces of stable sheaves on K3 surfaces. Moreover, I would like to discuss relations between automorphisms on moduli spaces and derived automorphisms of K3 surfaces and compare their topological/categorical entropy.
